[dawn][native] Make DisposeCallback a callback instead of fnptr

This allows the C++ API improvements of webgpu_cpp.h to be used with thi
type. It required wrapping it in a DisposeCallbackInfo with a
CallbackMode.

Update the implementation to use a TrackedEvent instead of a TrackedTask
now that there is a CallbackMode.

Update tests accordingly and use the MockCppCallback helper.

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.
