Fetch third_party/node via CIPD

Switches from using a GCS hook for third_party/node to a CIPD
dependency. This is specifically being added to unblock some work
related to running WebGPU CTS tests on all platforms in the gn_v2
recipe, but should also be a quality of life improvement for managing
this dependency.

The requested version remains unchanged, but should be easy to change in
the future. The version that is currently used is >2 years old at this
point.

NOTE: Due to this switch, the paths on Linux and Mac have changed
slightly since there is no longer an intermediate directory between
//third_party/node/ and the actual package contents. However, because
of caching on the bots, the old GCS-fetched data may persist for up to a
week after this lands. As such, it is possible that failures will start
occurring at a later point if the old paths are still used somewhere. If
this occurs, it is likely better to fix the problematic paths instead of
reverting this.

Similarly, the GCS-fetched data will likely remain in local checkouts.
This is not expected to cause any issues, but users can delete the
contents of third_party/node/ and re-run "gclient sync" to remove it if
desired. "gclient sync -D" does not appear to clean this up
automatically.

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.
