Roll third_party/webgpu-cts/ 18f1cc77d..b62c3fc76 (3 commits)

Updated expectations:
 - dawn prohibits copying to textures in certain tier1 formats, when it
   should allow it
     - Skip webgpu:web_platform test because they generate so much output it
       causes timeouts.
     - mark webgpu:api tests as Failure
 - mac AMD fails on certain textureLoad cases with depth24plus-stencil8 format
 - skip two test groups for Pixel 4 because they are flaky and can timeout
 - suppress flaky FXC compiler crashes on shader validation of
   add/sub/mul expressions

Regenerated:

 - compat-expectations.txt
 - ts_sources.txt
 - test_list.txt
 - resource_files.txt
 - webtest .html files

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
