[tint][ir][fuzz] Refactor IR fuzzer infra to impl pre/post validation

This change hoists the bespoke code from a variety of fuzzer
implementation for doing post-run validation up into the fuzzer runner
code, so that copy-paste errors and capability omissions are more
difficult.

Fuzzer creation now takes in either a single Capability set that is
used for validation before and after a run, or a pair of Capability
sets, one for before validation and one for post validation.

This required having the fuzzer impl function return whether or not
the run was successful, thus whether or not post-validation should
occur. Instead of using a simple bool, the Result<SuccessType> that
many transform impls return was instead used, so these impls could be
passed into the fuzzing infra with less boiler plate.

Some fuzzing passes that previously did not perform a post-validation
step now do with this change.

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.
