Implement upstream RequestDevice, add native-only CreateDevice 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 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:
