Add Wayland support

[greatest-ape]

A good starting point could be https://github.com/Smithay/wayland-rs/blob/master/wayland-client/examples/simple_window.rs

Is there even a way to do something similar to reparenting that works across compositors yet? There's the xdg-foreign-unstable-v2 spec but I don't think GNOME plans on supporting it: https://wayland.app/protocols/xdg-foreign-unstable-v2

Hmm, there might not be.

Any updates?
