8e957160b1 Use Tint SingleEntryPoint transform in Vulkan/GL backends
Some Vulkan drivers don't handle multiple entrypoints well.
In addition, SPIRV-Cross translation can be wrong for
shader modules with multiple entrypoints. Always emit a single
SPIR-V entrypoint to workaround these issues.

This allows updating CopyTextureForBrowser to use a single
shader module, and it fixes some tests with multiple
entrypoints.

9749f5a9f5 Move a function to TextureFormatUtils.h|.cpp and rename these two util files
This change moves function ViewDimensionToTextureDimension() to
TextureFormatUtils.h|.cpp.

This change also renames TextureFormatUtils.h|.cpp to TextureUtils.h|.cpp
because the new name makes more sense now.

a5f24e590a Validate textures with filtering/non-filtering/comparison samplers
Renames dawn_native::ComponentTypeBit to SampleTypeBit and makes
the bitmask match wgpu::TextureSampleType. wgpu::TextureComponentType
should be removed in a follow-up CL.

The Format table is augmented with float/unfilterable-float information
so that textures can be validated against the BGLEntry's
TextureSampleType.

EntryPointMetadata::ShaderBindingInfo no longer inherits BindingInfo
because the two types are diverging further. Most notably, this CL
reflects from Tint the supported SampleTypeBits for texture bindings.
This bitset is validated against the bind group layout.

Adds an isFiltering getter to SamplerBase. A filtering sampler must
not be used with a non-filtering sampler binding.

Lastly, the CL reflects sampler/texture pairs from Tint and validates
an entrypoint against the pipeline layout that a filtering sampler is
not used with an unfilterable-float texture binding.

0d50a2c770 ComputePipelineDescriptor.computeStage->compute
Deprecates the computeStage member of the descriptor in favor of compute

breaking backwards compatibility some code had to be manually added to
the wire client to copy from the deprecated member to the new one and
visa versa.

e688e52e6c D3D12: Disable GBV when using partial validation.
GBV's ability to patch shaders with validation code
was hanging several end2end tests. Since disabling
GBV shader patching would render partial validation
ineffective, partial validation was re-mapped to have
GBV disabled while full validation enables GBV by default.

End2end tests now default to partial validation so
tests that would otherwise not run with GBV can still
have some coverage.

16036cf206 Add WGPU_STRIDE_UNDEFINED and update bytesPerRow/rowsPerImage validation
This makes a nearly one-to-one mapping between the JS and C APIs, which
benefits projects like Blink and Emscripten.

- JavaScript's `undefined` is equivalent to C `WGPU_STRIDE_UNDEFINED`.
- JavaScript's `0` is equivalent to C `0`.
- To implement the API correctly, Blink must special-case an actual
  value coming in from JS that is equal to WGPU_STRIDE_UNDEFINED
  (0xFFFF'FFFF), and inject an error.

Keeps but deprecates a reasonable approximation of the old behavior.

db8766bb23 Support internal pipelines for Dawn
Like copyTextureCHROMIUM in Chromium, CopyImageBitmapToTexture can use
internal pipeline to do the GPU uploading. But Dawn doesn't support
internal pipeline now.

This patch adds the first internal pipeline for Dawn and add the API
CopyTextureForBrowser to use internal pipeline to do gpu uploading.

The patch integrates very simple wgsl vertex/fragment shaders to do
simple direct blit to verify the whole system works.
