Tint/HLSL: Implement AST transform for pixel local variables

This patch implements the AST transform "pixel_local" for pixel local
variables on Tint HLSL backends.

Below are the steps that the transform "pixel_local" do:
1. Translate the var<pixel_local> varaible into a var<private> and a
   bunch of read-write storage textures with an internal attribute
   "rasterizer ordered view".
2. Call function "load_from_pixel_local_storage()" before the original
   main function to load the data from the read-write storage textures
   added in step 1 into the var<private> variable.
3. Call function "store_into_pixel_local_storage()" after the original
   main function to store the data from the var<private> variable into
   the read-write storage textures added in step 1.

Test: tint_unittests

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.
