[tools] Add a new 'fuzz' tool

A wrapper around tint's libFuzzer executables which:
* Uses a tmp directory for output, reducing SSD cycles, and avoiding files being sprayed into the repo
* Provides a --check flag for verifying that the fuzzers don't error on the ./test/tint files.
* Uses the ./test/tint tree as the default corpus directory
* Runs NumCPU instances by default.
* Stops at the first error

Add this to Kokoro presubmits to ensure we don't accidentally break the fuzzers.

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.
