5397f9f9d0 Add basic or stub implementations of upstream instance/adapter APIs
Adds upstream instance/adapter APIs. In dawn_native, the basic APIs
to get limits and properties are implemented, but requestAdapter and
requestDevice are not. In dawn_wire, nothing is implemented, but the
stub definitions are put in place, as well the mechanism to inject
WGPUInstance into the wire.

There is a lifetime concern with WGPUInstance and WGPUAdapter on the
wire in that we need to ensure that the client cannot free the
instance or adapter while they are in use. In the near term, this is
not a problem because Chromium will always hold ownership of the
instance and adapters outside of the wire - i.e. it won't inject and
then release ownership.

652293f14c Support multiple Vulkan instances in the Vulkan backend
This will allow the Vulkan backend connection to be initialized, and
then selectively discover adapters on just one of the instances.
This is needed so that discovery of the fallback WebGPU adapter can
avoid initializing any adapters other than SwiftShader.

2d0007ca8f Don't connect to backends that aren't needed
Change backend connection in Instance.cpp to store a bitset of
backends that have been connected. This lets us only connect to a
single backend if AdapterDiscoveryOptions are passed explicitly,
and track which connections have/have not been made. Later, we can
connect to the rest of the backends if more are requested.

This is part of some improvements to the existing code so we can
selectively discover adapters and control discovery of the
high-performance, low-power, and fallback WebGPU adapters.

5e1ca53269 D3D12: Support creating compute pipeline asynchronously
This patch implements the asynchronous path of CreateComputePipelineAsync
on D3D12 backend with the basic framework of the dawn_unittest
AsyncTaskTest.Basic.

1. Call the constructor of dawn_native::d3d12::ComputePipeline in the main
   thread.
2. Execute dawn_native::ComputePipelineBase::Initialize() (a virtual function)
   asynchronously.
3. Ensure every operation in dawn_native::d3d12::ComputePipeline::Initialize()
   is thread-safe (PersistentCache).
4. Save all the return values (pipeline object or error message, userdata, etc)
   in a CreateComputePipelineAsyncWaitableCallbackTask object and insert this
   callback task into CallbackTaskManager.
5. In Callback.Finish():
- Insert the pipeline object into the pipeline cache if necessary
- Call WGPUCreateComputePipelineAsyncCallback

Note that as we always handle the front-end pipeline cache in the main thread,
we don't need to make it thread-safe right now.

aa0e1be0e8 Reland "Vulkan: Fallback to XCB for Xlib surfaces"
This is a reland of fb0bf70459c44b31419400598b592eaaae85f932

Reland after making libx11-xcb dynamically loaded since it isn't present
on all Linux deployment targets of Chromium. Also includes a couple of
additional cosmetic changes to d3d12/PlatformFunctions noticed while
looking at it for inspiration.

Original change's description:
> Vulkan: Fallback to XCB for Xlib surfaces
>
> Chromium builds the Vulkan loader without support Xlib (because it
> prefers XCB) which caused Xlib wgpu::SwapChain creation to fail on the
> Vulkan backend.
>
> This CL adds a fallback to use VK_KHR_xcb_surface if VK_KHR_xlib_surface

Implements a new opengl::AdapterDiscoveryOptionsES subclass to specify its creation at adapter discovery time.
Adds a "-b opengles" command-line flag to the code samples.
Asserts on a call to glShaderStorageBlockBinding() on ES.
Works around missing indexed draw buffers support by asserting when a non-0 color attachment is specified.
Works around missing glClearTexSubImage() by asserting. :/
These will likely require front-end validation.

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).

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

review.

allocated on the heap and forces the caller to use unique_ptr when
calling AcquireError.

15d4c2e63b Emulate store and multisample resolve on Metal
This patch implements "store and MSAA resolve" store operation on Metal
drivers that don't support MTLStoreActionStoreAndMultisampleResolve with
a workaround that does MSAA resolve in another render pass.

Driver workaround is one type of Dawn Toggles. Dawn Toggles will include
other optional optimizations and features that can be configured to use
or not when we create Dawn Devices.

As all Metal try bots don't need this toggle, to better test this
patch on the try bots:
1. We add the support of forcing enabling a workaround when starting an
   Dawn end2end test so that we can test the workaround on the platforms
   where the workaround is disabled.
2. We add an optional parameter DeviceDescriptor to CreateDevice() so
   that we can custom the toggles the Dawn device should use.

This patch also adds the support of querying toggle details from Instance
and the names of the toggles in use from Device. These APIs are tested in
the Dawn unittests added in this patch.

d030f64550 Reorder backend connections so that explicit APIs come first
This makes it so that default adapter discovery finds
Metal/D3D12/Vulkan first.

90e594ee8b OpenGL: Implement the backend connection and adapter.
The OpenGL backend can't gather discover default adapters because it
needs getProc to do anything so we add DiscoverAdapters method to
Instance that takes backend-specific options.

dawn_native::opengl::CreateDevice is removed in favor of the adapter
path so OpenGLBinding is modified to create an instance locally. This is
only temporary until all backends support adapters, at which point a lot
of *Binding code will be factored.

Also contains a small fix for Result<T, E> with movable types.

ac67fec1c9 dawn_native: Add Instance and Adapters
New objects are introduced to control what happens before device
creation in dawn_native:
 - Instance: a connection from the application to dawn_native that is
used for dependency injection and to discover adapters.
 - Adapters: represents the possibility of device creation for a specific
(GPU, backend) pair.
 - BackendConnection: an internal object that standardizes the interface
between the frontend and backends.

The BackendConnection interface is implemented for the Null backend and
stubbed out in other backends. This allows this change to port the
ValidationTests to use the new Instance and Adapters concept and deal
with other backends later.
