Add generating Tint IR fuzzer corpus

This adds in a Python script for generating IR binary file from a WGSL
file, build rules for running this over the testing WGSL files, and
changes to the IR binary outputting code to reduce the number of
failures due to unsupported inputs.

Currently 7203 out of 7275 shaders that are used in the WGSL corpus
are convertable. Those that are not, either use enables that are not
supported in the IR, or fail for reasons like missing override
values. The generation code is resiliant enough that these failure do
not break process, so investigating those failing shaders can be done
in a follow up CL/issue.

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.
