[tint][fuzz] Add fuzzer corpora minimization

This CL does a major rework of how fuzzer corpora are generated in
anticipation of moving to storing them in GCS. Future CLs and work
will be needed to migrate to using GCS.

- Reworks corpus generation into a single script
  'generate_tint_corpus.py'
- Changes 'ir_fuzz_as' command line args to support either one file
  being assembled or a directory of files being assembled
- Reworks GN rules to have a non-minimized and minimized generation
  actions for WGSL and IR, which have appropriate dependencies.
- Explicitly added the non-minimized corpora as dependencies to the
  fuzzer targets. Since they are low cost to generate but are needed
  for things like the fuzz check in the CQ.
- The minimized rules are not used as dependencies to avoid dependency
  loops and keep build time manageable, since minimization can take a
  long time).

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.
