[dawn][native] Re-order EventManager callback vs tracking.

- With spontaneous events in the work, it became possible for races
  where a two threads can race on checking if an event was tracked.
  As a result, we need to guarantee that callbacks have been fired
  before untracking events. Otherwise, races could see that an
  event was untracked, assume it's complete, but find that it
  wasn't actually fully complete yet since the other thread didn't
  run the callback yet.

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.
