Revert "[dawn][metal] Makes AllowSpontaneous work for Metal queue events."

This reverts commit b1c66af72925e24732b7c0f7c7275714d960b842.

Reason for revert: Failures on Intel and AMD Macs, e.g.:
https://ci.chromium.org/ui/p/chromium/builders/ci/Dawn%20Mac%20x64%20DEPS%20Release%20%28AMD%29

Bug: 412761367
Original change's description:
> [dawn][metal] Makes AllowSpontaneous work for Metal queue events.
>
> - Since the queues in Metal are updated via Metal callbacks already,
>   we can make AllowSpontaneous work by having the Metal callbacks
>   directly call the queue callbacks as well.
> - Adds spontaneous tests for queue events in Metal.

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.
