Add validation for Framebuffer Fetch

This adds the reflection of the framebuffer inputs from Tint, and
validation that these inputs match the render pipeline's color state.

Also adds tests, docs, rename a couple identifiers and restructure the
ColorState validation to do less casting.

Tests found the following bugs during development:
 - Forgot to skip over unused framebuffer inputs during validation.
 - Forget to update SetWGSLExtensionAllowList.
 - Indexed with I instead of J in a test.

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.
