Austin Eng d761d5a575 Add Chromium's StackVector base class and ityp::stack_vec
In order to lift Dawn's restriction on the number of bindings
per bind group, static sized arays need to be converted to
dynamically sized vectors. This CL adds Chromium's StackVector
class which behaves like std::vector but provides a stack allocator
to allocate small vectors on the stack. Dawn can use this to avoid
making separate heap allocations for a smaller, realistic binding
counts.

The CL also adds an ityp::stack_vec class to support using
a StackVector with TypedInteger indices.

Austin Eng 7a4685f448 Add TypedInteger
This CL adds a TypedInteger helper which provides additional type
safety in Dawn. It is a compile-time restriction that prevents integers
of different types from being used interchangably in Debug builds.

It also adds ityp::{array,bitset,span} as helper classes to wrap std::
versions (not span). These accept a template paramter as the Index type
so that typed integers, or enum classes, may be used as a type-safe
index.

For now, bind group layout binding indices use TypedInteger. Future
CLs will convert other indices to be type-safe as well.

Corentin Wallez 13110bff05 d3d12_platform: ensure windows.h macros don't cause compile errors
The windows.h macros were undefined only at the end of this platform
header previously but with the addition of d3d12sdklayers.h the
definition of ID3D12DebugQueue::GetMessage picked up the macro and
became GetMessageA or GetMessageW, but Dawn code referred to it as
GetMessage causing a compilation error.

Fix this by preemptively loading windows.h and undefing some of the
macros so that the D3D12 headers don't see them.

 - Adding a dummy argument to AddTraceEvent so that the __VA_ARGS__ is
never empty in TraceEvent.h and doesn't require __VA_ARGS__ token
pasting with a comma.
 - Extracting the first parameter in DAWN_INSTANTIATE_TEST with some
preprocessor tricks instead of singling it out, to avoid __VA_ARGS__
token pasting with a comma.

Wmicrosoft-enum-value is fixed by a previous spirv-cross roll that fixes

Instead of directly populating GPU heaps, pre-encoded
BindGroups are staged on CPU heaps then copied over
to the GPU. Non-shader visible allocators are stored
on the BGL, which hands out fixed-size chunks to

CPU allocations are tied to the lifetime of BindGroup

Corentin Wallez ba53617f6f Vulkan: Load functions for surface extensions we support.
Previously the surface extensions were only enabled so we could import
VkSurfaceKHR's created from GLFW. To implement the webgpu.h
surface-based swapchains, we are going to use the extension entrypoints
too.

This changes vulkan_platform.h to set defines that make vulkan.h expose
the entrypoints and datatypes for all the Vulkan extensions we might
care about for a given compilation configuration.

Kai Ninomiya f44a809f9a Remove VK_DEFINE_NON_DISPATCHABLE_HANDLE magic, use explicit VkHandle wrapper
Overriding VK_DEFINE_NON_DISPATCHABLE_HANDLE changes the function
signatures of Vulkan functions, changing their ABI and making us
incompatible with real drivers. This removes that magic, and replaces it
with an explicit wrapper, VkHandle, which has much of the same
functionality as the original VkNonDispatchableHandle.

It adds definitions for dawn_native::vulkan::VkBuffer et al, which
shadow the native ::VkBuffer et al. This retains type safety throughout
the Vulkan backend without changing every single usage.

Notably, the following things had to change:
- An explicit conversion from VkBuffer* to ::VkBuffer* is needed for
  arrays. This is implemented as a reinterpret_cast, which is still
  safe as the new VkHandle still has the same memory layout properties
  as VkNonDispatchableHandle did.
- When pointing to a VkHandle as an output pointer, it's now necessary
  to explicitly get the native ::VkBuffer (via operator*) and point to
  it.

Corentin Wallez 3a1746e71c Introduce wgpu::Surface and implement it for HWND, X11 and Metal
This is another step to implement webgpu.h swapchains, Surface is
essentially a union type of all the types of windows that can be used to
create swapchains.

Changes to allow implementing wgpu::Surface and test its creation are:

 - Add GLFWUtils.cpp/.h/_metal.mm  that contains helpers used to use
WebGPU with GLFW. This deprecates BackendBinding.h that will be removed
when the NXT swapchain is removed.
 - Add a `dawn_use_x11` GN variable to factor all the places in BUILD.gn
where we checked whether we should use X11.
 - Add a `supports_glfw_for_windowing` GN variable in the main BUILD.gn
file to control which configuration tests and samples using GLFW can be
built.
 - Add a ObjCUtils.h to contain some ObjC functionality that we'd need
in files that otherwise would be C++ (so that they can be compiled on
all platforms).

Rafael Cintron 69c68d01b2 Improve Memory Management of Result class
The way in which the Result class is used in Dawn can be fragile
with respect to memory management because the caller of AcquireError
must know they need to delete the returned pointer or a memory leak
will occur. We've had a couple of instances where developers have
accidentally left out the delete call and managed to get past code
review.

This CL changes the Result class so that it assumes the error is
allocated on the heap and forces the caller to use unique_ptr when
calling AcquireError.

The Fuchsia platforms relies on a number of Vulkan extensions
that have not been upstreamed to Khronos yet, and thus are not
part of the official Vulkan headers (i.e. <vulkan/vulkan.h>).

This CL adds a new header under src/common/ that contains these
declarations, extracted from the Fuchsia source tree, and ensures
they are included automatically from <common/vulkan_platform.h>

This is necessary to support certain features when building
Dawn on Fuchsia.

IMPORTANT NOTE: Some of the things declared in this header will
change once everything is upstreamed, which will require updating
the source code using them. For example,

  VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_TEMP_ZIRCON_EVENT_BIT_FUCHSIA

Will likely be renamed officially as:

  VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_ZIRCON_EVENT_BIT

And will be assigned a new value by Khronos.

David 'Digit' Turner b749d07ac9 Enable Vulkan for Chromium Fuchsia build.
Enable the Vulkan backend when building Dawn with
the Chromium build system for Fuchsia. To make this
work properly the following is required:

- Modify VulkanInfo.cpp and BackendVk.cpp to correctly probe
  the Fuchsia swapchain layer and its layer extension, as well
  as enabling them when creating a new VkInstance.

- Modify VulkanFunctions.cpp to load the Fuchsia swapchain
  related extension for this platform only.

- Provide a small mock GLFW library for Fuchsia under
  src/utils/Glfw3Fuchsia.cpp, since the upstream project
  does not support this platform at all. Its purpose is
  only to allow the creation of the right VulkanBinding
  instance, which depends on the creation of a display
  surface for latter swapchain creation.

- Add //third_party/fuchsia-sdk:vulkan_base and
  //third_party/fuchsia-sdk:vulkan_validation as
  data_deps of the libdawn_native_sources target in
  order to ensure that the Fuchsia package created by
  the build system will include the correct Vulkan
  libraries (loader and validation layers).

This builds correctly, and both dawn_unittests and
dawn_end2end_tests will run on a real Fuchsia device
or inside the Fuchsia emulator, using either GPU
virtualization or a software-based renderer.

Note: dawn_unittests will also run inside QEMU, but
not dawn_end2end_tests, since the latter requires
proper GPU emulation which is not available in this
environment.

NOTE: All end2end tests pass using a device with
      an "Intel HD Graphics 615 (Kaby Lake GT2)"
      adapter. However:

       - For some reason, a single test takes up
         to 129 seconds to pass
	 (BufferSetSubDataTests.ManySetSubData/Vulkan).

       - The test process crashes inside VkDestroyInstance(),
         apparently inside the Fuchsia-specific imagepipe
	 layer (which implements swapchain support).
	 This is likely a bug in the layer itself, and
	 not Dawn.

    Also, may end2end tests will crash when run inside
    the Fuchsia emulator (which uses GPU virtualization
    to talk to the host GPU). The crashes happen inside
    libvulkan-goldfish.so, the emulator-specific Vulkan
    ICD on this sytem. Not a Dawn bug either.

Brian Ho ee3de1e1f3 Remove undefined behavior from NextPowerOfTwo
This CL removes undefined behavior from NextPowerOfTwo(0). Currently on
Linux, calling NextPowerOfTwo(0) simplifies down to:
  - 1ull << (64 - __builtin_clzll(0 - 1));
  - 1ull << (64 - __builtin_clzll(INT_MAX));
  - 1ull << (64 - 0);
  - 1ull << 64

Since 64 is the same width as the long long in our left operand, this
left shift results in undefined behavior (C++11 standard 5.8.1). For a
default Chrome compile, this does not cause any issues; 1ull << 64
results in 0.

In ChromeOS, however, we compile with ThinLTO which, among other things,
inlines various functions in the interest of performance. When
NextPowerOfTwo is inlined, the undefined behavior of our invalid left
shift borks the stack which causes the Math.NextPowerOfTwo unit test to
fail.

BUG= chromium:993457

Yan, Shaobo 351ea23830 Dynamic Buffer Offset : D3D Backend
In a typical graphics application it is a common usage to update some uniforms once per draw,
and such uniforms include the word positions, orientations, and so on. In the current state of
WebGPU, this means that for each draw call we have to create a new bind group to set the right
uniform values. Bind group creation is expected to be more expensive than
recording draws because a memory allocation is required.

The functionality of dynamic buffer offset is to reduce the number of bind groups that need to
be created.

The patch implements dynamic buffer offset on D3D backend using root descriptor.

David 'Digit' Turner 56a21a6151 Make GN //src/common target easier to use when Vulkan is enabled.
Ensure that //src/common exports the appropriate config settings
when vulkan is enabled. This CL tries to address several issues
at once:

- A target that depends on //src/common and wants to find
  "common/vulkan_platform.h" needs to have "${dawn_root}/src"
  in its include_dir.

- Same target needs to have DAWN_ENABLE_VULKAN macro to avoid
  a compile #error message when including "common/vulkan_platform.h"

- Same target needs to be able to find <vulkan/vulkan.h> which
  is included by "common/vulkan_platform.h".

This is achieved by ensuring that the "dawn_internal" config,
is provided as a public_config by the GN ":common" target.
And by adding third_party/vulkan_headers as a public_deps
if |dawn_enable_vulkan| is true.

Note that "dawn_internal" is used by several other targets
in Dawn BUILD.gn files, hence why it was not renamed to something
else like "dawn_common_config" here.

+ Simplify targets that currently depend on ":common" so they
  no longer need to add vulkan_headers as an explicit dependency.

Corentin Wallez 431d618961 Add most WebGPU texture formats on Vulkan
This adds the formats to dawn.json, implements support in the Vulkan
backend and adds tests performing basic sampling checks for all formats.

The R8UnormSrgb and RG8UnormSrgb formats skipped because they are not
required in Vulkan (and RG8UnormSrgb is in fact not supported on the
machine used for developing this CL). A PR will be sent to the WebGPU
repo to remove the from the initial list of formats.

The RG11B10Float and RGB10A2Unorm formats of WebGPU are replaced with
B10GR11Float and A2RGB10Unorm that are the formats exposed by Vulkan. It
is likely that all APIs implement them with components stored in that
order.

Each format except depth-stencil ones is tested by uploading some
interesting texel data and checking that sampling from the texture
produces correct results. The goal is to make sure that backends don't
make a mistake in the giant switch statements. There was no effort made
to check the hardware implementation of the formats.

Tests will later be extended to cover rendering and clearing operations
as well as multisample resolve.

It isn't clear if depth-stencil format will support TRANSFER operations
in WebGPU so these are left untested for now.

Corentin Wallez 91e949292f BUILD.gn: put public include dirs in all_dependent_configs
The public include dirs for Dawn were in the dawn_public config but it
would only be added to targets as a part of public_configs. This meant
that second-level dependencies that ended up needing to include
dawn/dawn.h wouldn't know where to find it.

Fixed this by adding include dirs in all_dependent_configs and renamed
the config to be very explicit that it is for include dirs only.
