Support dawn.node on Swarming

Updates run_dawn_node_cts.py to have the underlying runner output
results to a temporary file, and if --isolated-script-test-output is
present, convert those results into a format that result_adapter can
ingest.

Ultimately, this means that the dawn_node_cts suite can now be run
on Swarming. The no_swarming mixin is removed as a result.

The format that the results are converted into is basically only
suitable for the current use of dawn_node_cts (ensuring that running via
Node is not completely broken). If testing via Node is ever expanded on
the bots, the conversion will need to be improved to a format that
supports multiple tests or native ResultDB integration will be needed.
In either case, the underlying runner's output format will also need to
be improved since it currently only gives a pass/fail per test without
any additional information.

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.
