[dawn][wire] Adds spontaneous wire mode.

- The new spontaneous wire mode makes it so that the server sets all
  callbacks to be spontaneous and immediately flushes the results to
  clients when applicable. Note that we do NOT flush immediately for
  logs in this change.
- Updates testing to run in this mode. To ensure that it's doing the
  right thing, also remove the explicit flushing of the
  server->client in this mode for the tests.
- Some minor modifications to TerribleCommandBuffer to handle cases
  where the client might be mid-Flush, but queue new commands.

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.
