Explicitly list Go architectures

Updates Dawn's Go dependency to explicitly fetch CIPD packages for all
supported architectures for an OS instead of relying on ${{platform}}.
Known users of this dependency are also updated to select the correct
copy based on the OS/arch combination at runtime. However, since the old
files are not automatically removed, it is possible that things may
break at a later point when the builder cache is cleared if a user of Go
was missed.

This is necessary in order to properly support running tests which use
the Go code under //tools/src on OSes that support multiple
architectures. Using ${{platform}} when fetching dependencies implicitly
assumes that the architecture of the machine fetching dependencies is
the same as the machine that will run tests. This assumption does not
hold true now that we support running tests on Swarming, as Mac in
particular prefers to build on arm64 regardless of which architecture is
being built for.

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.
