[dawn][wire] Fix dawn wire server to use ProcessEvents.

- The wire server should currently (by default) be using
  ProcessEvents for most callbacks. Otherwise, it's possible
  for races since the wire is not currently thread safe.
- Note that requestAdapter and requestDevice are currently
  exceptions.
- In the future, once the wire is thread-safe, we should be
  able to forward the callback mode accordingly instead of
  forcing all wire server callbacks to be ProcessEvents.

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.
