Explicitly list Node architectures

Updates Dawn's NodeJS dependency to explicitly fetch CIPD packages for
all supported architectures for an OS instead of relying on
${{platform}}. Users of this dependency are also updated to select the
correct copy based on the OS/arch combination at runtime.

This is necessary in order to properly support running Node-based tests
on OSes that support multiple architectures. Using ${{platform}} when
fetching dependencies implicitly assumes that the architecture of the
machine fetching dependencies/building 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.
