[tint][cmake] Use build protoc instead of system installed version

The existing cmake rule will use the first protoc that shows up in your
path, so will likely default to the system installed version of protoc,
which may not be compatible with the version of libprotobuf in our repo.
Additionally this can lead to build failures when there is no installed
protoc, and the output path for the build is not in the path.

This also include a small fix for '"--${ARGS_LANGUAGE}_out', since
protoc uses '--<flag>=<arg>' or '-<flag><arg>' format for its CLI, not
'--<flag> <arg>'. And it was using the wrong variable name.

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.
