run-cts: Run a batch of test cases per runner process

Add -batch-size to run-cts standalone, the most test cases per runner
process (default 500); fewer than -j times that many are split evenly
over the -j workers. The workers take batches from a shared queue, run
each in one runner process and report the results as they arrive. A
watchdog kills a process that reports no result within -case-timeout,
plus -startup-allowance for the first one. When a process ends with
cases left, the case it was running is reported with its output and the
rest of the batch as not run. node -isolate uses the same code with one
test case per process.

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.
