Convert Standalone Builders to chromium wrappers

Converts the experimental standalone Dawn builders to use the wrappers
provided by the @chromium-luci package. This allows us to fully define
builders src-side instead of having to split them between the Dawn repo
and the build repo.

Tests are still defined using the older buildbot JSON approach since
we want to keep the Swarming dimensions in sync with Chromium's. We may
be able to roll in Starlark-defined dimensions at some point in the
future, but the JSON approach should work until that is demonstrated
to work.

Should be landed in conjunction with crrev.com/c/6808555 to fully move
the standalone Dawn builders into the Dawn repo.

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.
