Revert "Roll reclient, buildtools; update related DEPS to match Chromium"

This reverts commit 2110deada3fe7fef7a1855c0fa30d9ddd8b9de6a.

Reason for revert: Still causing a bunch of mac flakes. Seems to be an issue with running reclient on mac11; may try using siso's own remoteexec instead of reclient.

Original change's description:
> Roll reclient, buildtools; update related DEPS to match Chromium
>
> This reverts commit c875dc549dc48b2a560b574d15035fe0af0ad00f
> and adds speculative fixes. The issue seemed to be related to
> buildtools, so roll buildtools to version from chromium 'main', and also
> update download_and_configure_reclient_cfgs to match Chromium 'main', at
> the same version I took the reclient release number from.

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.
