[tint][ir] Build IR Binary by default in CMake

This will default building libprotobuf also, but does not build the
fuzzers by default.

This can still be explicitly turned off by a dev/embedder if desired.

This more closely aligns with the behaviour that the GN builds have, and
will reduce the likelihood of breaking changes for this code landing,
since devs will see these breakages by default and the CQ should now
catch it.

This also adds missing coverage for the IR fuzzer on the CQ, since it
will be run via a wrapper in the WGSL fuzzer during `./tools/run fuzz
--check` for certain bots . (`fuzz --check` not running for GN bots is a
KI and being worked on).

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.
