b1870eff04 [spirv-writer] Add a LocalSize execution mode.
In SPIR-V a compute entry point requires a WorkGroup Size constant or a
LocalSize execution mode. This CL adds a 1,1,1 execution mode as a
starting point.

a6d7f56cf8 Add resource usage tests in a single draw/dispatch
It is invalid to read and write on the same buffer/texture in
a single draw or dispatch. This change adds tests to cover this
situation.

Note that we have already added resource usage tests between passes
in the same command buffer, and tests between draw or dispatch calls
in the same pass. And this patch adds tests inside a draw or dispatch
call.

303a3daf0d D3D12: Decouple descriptor heap allocations.
Allows bindgroups to be populated by heap type. Previously, failing to
populate one type of GPU descriptor heap required both GPU heaps
to be switched out. This resulted in extra copies and heap allocations
should only one heap type overflow.

This change also simplifies GPU descriptor heap management:
- Allocator no longer needs to operate on both heaps.
- Sub-allocation tracking can be moved into handles.

A follow-up change will remove duplicated sampler heap allocations.

2d79ef264e Do not use Dawn's warnings for compiling Chromium's gtest main.
When building in Chromium, Dawn's gtest targets use sources files
in Chromium so it can use Chromium's GTest harness. These source
files were compiled with the "dawn_internal" config included.
This made them include Dawn-specific warnings that trigger on parts
of Chromium's //base.

Instead compile these "main" files as separate source_sets without
dawn_internal and link them in the dawn test executables.

c94f4a7a19 D3D12: Fix invalid allocation size check.
GetResourceAllocationInfo() returns UINT_MAX64 when
the requested size is too large. This corrects the
validation to OOM when D3D considers the size
invalid.

Only validating for zero-size would cause a device
loss as certain D3D drivers may not always consider
zero-sized invalid and NextPowerOfTwo(UINT_MAX64)
would overflow the allocator.

88f2ec853f Add basic supports of readonly and writeonly storage textures on Metal
This patch adds the basic supports of both read-only and write-only
storage textures on Metal with several simple end2end tests that use
read-only or write-only storage textures in every shader stage.

Here are the follow-ups after this patch:
1. test all the texture formats that can be used as both read-only and
write-only storage textures.
2. support using a texture with multiple different binding types in one
rendering or compute encoders.
3. test image2DArray, imageCube and imageCubeArray.

228392558f [spirv-writer] Add start of break and continue.
This CL adds the beginning of break and continue support. The
conditional versions are not supported, just the non-conditional.

f70db58dce Fix MSVC compilation.
Add missing includes:
- Add missing vector include WGPUHelper.h
- Add missing algorithm include as there is a std::transform used in DawnPerfTestPlatform.cpp

Remove c++20 designated initializers from tests.
Removing these as we target c++14 and they trigger warnings in MSVC.

a92c114c1a [spirv-reader] Label control flow constructs
Label basic blocks with:
- their nearest enclosing structured control flow constructs.
- their nearest enclosing continue construct, if any
- their nearest enclosing loop construct, if any

A construct consists of a span of blocks in the computed block order.
It knows its parent construct, if any, and its nesting depth.
