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

This CL implements RequestDevice and also has changes for Dawn to internally use wgpu::FeatureName enums, instead of strings. Some of the string handling is kept for now to support the deprecated creation path. GetFeatureInfo is added to the instance to get a name and description of the feature, for reporting in about://gpu. Dawn device toggles are now passed in an extension struct off of the device descriptor. This is only supported in dawn_native, and not dawn_wire, for now, since dawn_wire doesn't have a way to serialize lists of null-terminated const char*. To enable the client to check whether the toggle descriptor is supported, a `dawn-native` feature is added which is supported all the time with dawn_native, but not supported with dawn_wire. Feature `dawn-native` also enables a synchronous version of CreateDevice for convenience.

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.h
version 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
