Re-enable Tint IR Fuzzer with fixes

This reverts commit d918947fbc48bb18033539189449d4ccd87cc397.

But retains and updates the custom GN rules for abseil-cpp

It drops the fuzztest and re2 DEPS, and insteads replaces the one
target needed by //testing in fuzztest with a mock no-op target, since
FuzzTest isn't currently used in Dawn.

Forking googletest/BUILD.gn is dropped

There are additional rolls on top of the original rolls to pick up
fixes I upstreamed.

This version should resolve the various duplicate symbols issues we
were seeing, and should allow rolling into Skia (via using a path
override in the new protobuf.gni)

Additional rolls:

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.
