Add the validation for PixelLocalStorage.

The AttachmentState is modified to contain the PLS state as it is part
of the compatibility between a render pass and a render pipeline.

Minimal fixes to dawn.json for GPU sizes.

Adds tests for the added validation.

Bugs found with tests:
 - The AttachmentState should different between no PLS and empty PLS.
 - Missing usage tracking.
 - Attachment state blueprint init didn't copy mHasPLS
 - Pipeline layout hash/equality wasn't updated for PLS.
 - webgpu_absl_format didn't handle no PLS vs. empty PLS.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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.
