Add dawn.node CTS to gn_v2 testers

Adds several runner scripts and makes the necessary build changes to
support running the dawn.node CTS on gn_v2 testers. This new test is
then added to dawn-linux-x64-sws-rel and its trybot mirrors.

This should be functionally equivalent to the "Run basic CTS test with
dawn.node" step on the testers using the older gn recipe.

Running these tests on Swarming is not supported yet, so they are run
directly on the builder.

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.
