This will help external projects that want to use Dawn, like Skia, refer to GN targets without GN discovering Dawn's main BUILD.gn file that causes all the tests and third_party dependencies to be discovered. This CL just splits off chunks of BUILD.gn into separate file, adds necessary includes and fixes up GN paths. It also introduces temporary groups for targets that are used in Chromium so that the paths can be fixed in a 3-way patch.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress 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.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
