[spirv] Add ForkExplicitLayoutTypes transform

Some storage classes require arrays and structures to have explicit
layout decorations, while others require them to not have any such
decorations. This transform forks structures that are shared between
those two storage classes to satisfy this SPIR-V validation.

When a type is forked, the transform introduces helper functions to
convert between the original type and the forked type for loads and
stores to the variable that needs the explicit layout decorations.

Array types will be handled in a follow up.

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.
