Fix cross-compilation for Windows on Mac/Linux

Somehow, these were the only fixes needed!

To do this, follow these instructions:
https://chromium.googlesource.com/chromium/src/+/main/docs/win_cross.md

Except on Mac, you may need to build with `autoninja --offline`. Siso
should work, but various system headers don't build when built remotely
(... though I actually have this problem occasionally with mac-on-mac
builds too). I'm getting a warning like this, which may be related:

  You have wrong version of reclient_cfgs not matched with third_party/llvm-build.
   cr_build_revision=llvmorg-23-init-10931-g20b6ec66-11,win
   reclient_cfgs=llvmorg-23-init-10931-g20b6ec66-11
  Make sure you have 'download_remoteexec_cfg' in .gclient custom_vars and run 'gclient runhooks'

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.
