e5d94c31a0 Fix a bug in ComputeTextureCopyBufferSize with empty copySize
This patch fixes a bug in buffer-to-texture and texture-to-buffer copies
when copySize.height == 0 or copySize.depth == 0. Previously we miss the
checks if either copySize.height or copySize.depth is 0 before doing
(copySize.height / blockHeight - 1) and (copySize.depth - 1) thus we
will get incorrect results because of arithmetic overflows.

This patch fixes this bug by adding the missed check and adds the
related regression tests in dawn_unittests

be637db589 Vulkan: Correctly request 16bit shader features.
All the querying of extensions was correctly handled for the WebGPU
ShaderFloat16 extensions, except that we forgot to request it when
creating the VkDevice.

In practice this doesn't crash as most drivers won't check if the
extension is enabled, and just compile the shader code correctly.
However the Vulkan Validation Layers complain. This CL fixes it by
requesting the features on device creation.

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.

Retrieval filter was receiving errors that shouldn't be

never reaching the storage filter or being stored without
being filtered, this workaround removes the storage
filter entirely and filters them upon being retrieved.

After the change, two new E2E tests fail

3fe84b5b33 Fix AssertAndIgnoreDeviceLossError to handle errors injected by fuzzer
Fuzzer recently started sometimes injecting errors with
CheckHRESULT returning E_FAKE_ERROR_FOR_TESTING, which needs to also be ignored
in AssertAndIgnoreDeviceLossError so that we can continue with destruction.

Rename AssertAndIgnoreDeviceLossError to IgnoreErrors

This CL also adds Austin's pretty printing of HRESULT results as hex values
and adds printing of "E_FAKE_ERROR_FOR_TESTING" error.

ac6bd4c98f Fix fuzzer hang when waiting for fence signal after device loss
When the fuzzer passes the command DeviceLoseForTesting, the
DawnWireServerFuzzer will hang forever when waiting for a fence signal
because the device was lost. This commit sets a callback on device loss
which gives an extra condition to break the hang.

59cfe3ea03 Clean up CopyTests
This patch does several clean-ups in CopyTests as a preparation of
supporting buffer-to-texture and texture-to-buffer copies with multiple
texture array layers.
1. Remove the zero-initialization of textures in CopyTests_B2T
2. Use a big buffer that contains the pixel data in all the texture
   array layers instead of several small ones that only contains one
   texture array layer.
3. Make CopyTests_T2T::DoTest() also use CopyTests::TextureSpec as its
   input parameter.
4. Add tests for the copies with multiple texture array layers. In this
   patch we just copy the data once per texture array layer, while in
   the next patch we will be able to copy the data for all the related
   texture array layers in one copy command.
5. Move some helper functions for copy tests to WGPUHelpers.cpp

fefb452f29 Reland: Vulkan: Enforce fixed subgroup size for compute shaders.
Reland after a refactor of how the extension handling work in the Vulkan
backend.

The original author is David Turner <david.turner.dev@gmail.com>.

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.

5cef1162b9 Reland: Vulkan: Report and enable subgroup size control device extension.
Reland after a refactor of how the extension handling work in the Vulkan
backend.

The original author is David Turner <david.turner.dev@gmail.com>.

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:

- 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.

- This modifies VulkanDeviceInfo::GatherDeviceInfo() to
  use PNextChainBuilder to query extension features and properties
  in a single call to vkGetPhysicalDevice{Properties,Features}2.

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.

984493d0ac Deprecate TextureCopyView::arrayLayer -> origin.z
All existing tests and samples are updated and deprecation tests added.

CommandEncoder still encodes using arrayLayers so the backends are
unchanged. They will be handled in a follow-up CL.
