Corentin Wallez 97ec825cde Vulkan: Don't use vulkan.h's prototypes.
VulkanFunctions handles the storing of Vulkan function pointers so Dawn
doesn't need the declarations for Vulkan entrypoints.

Yunchao He 3665d28e6e Add validation tests for resource usage tracking
This change mainly does a code refactoring. It moves resource tracking
tests from CommandBufferValidationTests.cpp to a separate test file.

It also adds a few tests, like copy dst/src doesn't impact resources
used in render/compute pass.

More tests about resource usage tracking will be added into this
separate test file.

Austin Eng 0847cb4637 Convert LayoutBindingInfo to an array of BindingInfos
This makes accessing per-index data simpler, and now that dynamic
buffer bindings are packed at the front, the old IterateBitset on
the dynamic buffer binding mask can be replaced with a simple loop
over the beginning bindings.

Jiawei Shao 0eff2a2b46 Add validations on the creation of bind groups with storage textures
This patch adds all the validations on the creation of bind groups with
read-only and write-only storage textures.

1. Only the textures with STORAGE usage can be used as read-only or
   write-only storage textures.
2. The format of the texture view used as read-only or write-only
   storage texture must match the corresponding declarations in the
   bind group layout.
3. The texture view dimension of the texture view used as read-only or
   write-only storage texture must match the corresponding declaration
   in the bind group layout.

Note that we don't test the match of the sample count because currently
we don't support sample count > 1 when creating a texture with STORAGE
usage and creating a bind group layout with read-only or write-only
storage textrue binding type.

This patch also adds a unit test to verify that it is invalid to create
a bind group layout with either read-only or write-only storage texture
binding type and dynamic offsets.

This patch also implements the bind group with storage textures on
Vulkan to make the Vulkan fuzzer happy with this patch.

This is a regression that was caught by the WebGPU CTS after
https://dawn-review.googlesource.com/c/dawn/+/17240 where the
BindGroupLayout validation was changed to use a set, and the check for
KMaxBindingsPerGroup removed.

Jiawei Shao 4a858a0cbd Reland "Check bind group layout with storage texture in pipeline descriptors"
This reverts commit 7c24b6b2ff.

Reason for revert: We can reland this CL now as the fix in shaderc has
been merged.

Note that the declaration whether a storage texture is multisampled or not
cannot be extracted correctly in SPVC. The fix in Dawn will be added after
it is fixed in shaderc.

Corentin Wallez 11652ff8f8 Implement the webgpu.h swapchains on Metal
The webgpu.h surface-based swapchains are implement on Metal which
required adding the present mode to NewSwapChainBase.

Additional automated tests are added which require getting the Instance
so a new getter is added to DawnTest. Additional some the state tracking
of swapchains is performed in the backend, so the
SwapChainValidationTests are turned into regular DawnTests so they can
check backends do the correct state tracking. To not lose coverage of
the Null backend, a NullBackend() DawnTestParam factory is added.

Finally swapchains cannot be entirely tested in an automated fashion, so
a new example is added called "ManualSwapChainTests" that allows
manually checking a number of properties. Documentation of the controls
and a manual test plan is in a comment at the top of the example's
source.

Austin Eng 83e138ca96 D3D12: Fix usage of CopyResource
CopyResource may only be used for resources that have exactly the same
format, dimension, mips, layers. And it can only be used if the entire
texture region is copied.

Ryan Harrison b988e03982 Add in a default case to unblock shaderc rolls
The roll in Chromium is failing, because Dawn doesn't handle all of the new enum
values, but I cannot land the 'proper' fix in Dawn, because Chromium doesn't yet
know about the new enum values. Yay, cross dependencies.

So my solution is land the default case in Dawn, land the DEPS roll in Chromium,
then patch in the 'proper' cases in Dawn.

This patch adds the basic validation of read-only storage texture,
write-only storage texture and read-write storage texture as new
binding types with no bind group layout provided in the creation of
pipeline state objects.

- Read-only storage textures can be used in vertex, fragment and
  compute shaders.
- Write-only storage textures can only be used in compute shaders
  due to the limitation on Metal.
- Read-write storage textures are not allowed now and they are
  reserved to be supported as an extension in the future.

Jiawei Shao 532be50b76 Check bindingType with shader stage when creating default pipeline layout
This patch intends to fix a crash issue when creating a rendering
pipeline with storage buffer declared in vertex shader and pipeline
layout is not set.

Without this patch, in PipelineLayoutBase::CreateDefault() the
bindingSlot.visibility is always set to Fragment and Compute when it is
a storage buffer, therefore a crash happens at the failure of the
assertion modules->IsCompatibleWithPipelineLayout() when the storage
buffer is actually declared in the vertex shader.

Bug: chromium:1059205

Original change's description:
> Vulkan: Report and enable subgroup size control device extension.
> 
> Certain Vulkan ICDs (Intel ones notably) will compile SPIR-V
> shaders with an liberal, compiler-selected, subgroup size (i.e.
> either 8, 16 or 32). For more context, see [1].
> 
> This can be a problem for compute, when one shader stores data
> in device memory using a subgroup-size dependent layout, to be
> consumed by a another shader. Problems arise when the compiler
> decides to compile both shaders with different subgroup sizes.
> 
> To work-around this, the VK_EXT_subgroup_size_control device
> extension was introduced recently: it allows the device to
> report the min/max subgroup sizes it provides, and allows
> the Vulkan program to control the subgroup size precisely
> if it wants to.
> 
> This patch adds support to the Vulkan backend to report and
> enable the extension if it is available. Note that:
> 
> - The corresponding VkStructureType enum values and
>   struct types are not rolled to the third-party Vulkan
>   headers used by Dawn yet, so vulkan_platform.h has been
>   modified to define them if necessary. This can be
>   removed in the future when the Vulkan-Headers are
>   updated in a different patch.
> 
> - This modifies VulkanDeviceInfo::GatherDeviceInfo() to
>   use VkGetPhysicalDevice{Properties2,Features2} if the
>   VK_KHR_get_device_properties2 instance extension is
>   available. Otherwise, the Vulkan 1.0 APIs
>   VkGetPhysicalDevice{Properties,Features} are used instead
>   (and it is assumed that no subgroup size control is
>   possible).
> 
> - This changes the definition of VulkanDeviceKnobs to
>   make room for the required pNext-linked chains of
>   extensions.
> 
> - A helper class, PNextChainBuilder is also provided in
>   UtilsVulkan.h to make it easy to build pNext-linked
>   extension struct chains at runtime, as required when
>   probing device propertires/features, or when
>   creating a new VkDevice handle.
> 
> Apart from that, there is no change in behaviour in this CL.
> I.e. a later CL might force a specific subgroup size for
> consistency, or introduce a new API to let Dawn clients
> select a fixed subgroup size.

Corentin Wallez 36f0388f79 Revert "Vulkan: Enforce fixed subgroup size for compute shaders."
This reverts commit 56f1678437.

Reason for revert: crbug.com/1059205
Bug: chromium:1059205

Original change's description:
> Vulkan: Enforce fixed subgroup size for compute shaders.
>
> This CL ensures that, on architectures with a varying subgroup size,
> compute shaders are always compiled with a fixed subgroup size to
> avoid consistency issues when one shader writes data in a subgroup-size
> dependent layout to GPU memory, to be read by another shader in a
> future dispatch.
>
> At the moment, only Intel ICDs are known to implement this [1],
> and the code uses a heuristics to chose the size of 16, which seems to
> be the sweet spot according to Intel engineers.
>
> + Update the PNextChainBuilder class to deal with the fact that
>   VkComputePipelineCreateInfo::pNext is defined as a const void*,
>   which created compiler errors in the previous implementation.

Corentin Wallez ddc5cacc27 GN: Use the hermetic XCode if available.
This matches Chromium's logic and make it less likely to break developer
workflow in the subsequent roll of Chromium's buildtools.
