CMake-only fork of https://dawn.googlesource.com/dawn with cleaned, vendored dependencies

Previously all of the device IDs I was aware of for a given vendor could be comfortably filtered with a single mask, but there's at least one exception that has come up since that indicates that support for multiple different masks per vendor is necessary. This change allows devices to be identified in groups, with each group being given a different mask or no mask at all. Architectures may be shared between groups. Also added the ability to mark a device group as internal, which will generate the helper functions (like `IsVendorArchitecture()`) for the internal architectures but not allow them to be exposed in GPUAdapterInfo. Internal device IDs may overlap with non-internal ones. Finally, added some validation logic to prevent duplicate deviceIds or conflicts between device sets/architectures. This was actually supposed to be in an earlier CL but somehow got omitted from the version that eventually landed.

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
- Tint is a compiler for the WebGPU Shader Language (WGSL).
