Dawn: Implement shader module front-end blob cache

This CL implement the blob cache for shader module front-end, currently
caching the reflection information, compilation messages, and validation
error (if any) into disk. With this CL, shader modules and pipelines can
be created without calling Tint and backend compilers at all on backends
supporting pipeline cache (i.e. D3D and vk) if cache hit.

This CL also make FeaturesSet and TogglesSet serializable so we can add
them in cache request.

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.
