Reland "Refactor AsyncTask into an object with helpers."

Added locking of AsyncTask's mutex while constructing the task. It is
possible that the task is run and completes before PostWorkerTask
returns.

This is a reland of commit 773146ed837bac5363753246e4e2ea3f476f20b1

Original change's description:
> Refactor AsyncTask into an object with helpers.
>
> AsyncTaskManager::PostTask now constructs a task object to wrap the
> running task and returns it. Allow for overriding the AsyncTask class
> with a template on PostTask.
>
> Update std::lock_guard to the more modern std::scoped_lock in
> AsyncTaskManager.

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.
