Revert "Refactor AsyncTask into an object with helpers."

This reverts commit 773146ed837bac5363753246e4e2ea3f476f20b1.

Reason for revert: I think this is causing CQ flakes like
https://ci.chromium.org/ui/p/dawn/builders/try/linux-clang-dbg-x86/b8704548794903932129/overview
[----------] 3 tests from AsyncTaskTest
[ RUN      ] AsyncTaskTest.Basic
[raw_hash_set.h : 3335] RAW: Use of destroyed hash table.


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.
