This change vendors `wgpu` library in-tree and hooks up the initialization bits. It implements adapter and device initialization and adds a simple test.
Current status:
- [x] Architecture
- [x] figure out the IPC story
- [ ] move wgpu crates into a dedicated folder (let's follow up with this)
- [x] Review
- [x] WebIDL changes by DOM peers
- [x] Linux
- [x] avoid depending on spirv_cross - https://github.com/gfx-rs/wgpu/pull/371
- [x] macOS
- [x] due to cross-compiling shaders - https://github.com/gfx-rs/gfx/pull/3047
- [x] need the dependency update

Update-1:
We decided to go with IPDL mechanism instead of Rust based ipc-channel (or any alternatives), which unblocks Windows build.
Update-2:
It appears that WebGPUThreading isn't needed any more as the child thread (and its event loop) is now managed by IPDL infrastructure. This PR removes it 🎉 .
Update-3:
InstanceProvider is also removed.
Update-4:
All set, the try is green, waiting for dependent changes to go in.
