wayland: Add support for xdg-shell protocol (unstable v6).
This is meant to be the desktop-enhanced version of wl_shell. Right now we just match what the existing wl_shell code does, but there are other areas of functionality available to us now, that we can fill in later. This uses the "unstable" API, since this is what ships in Ubuntu 17.10 (as part of Wayland 1.10), but Wayland 1.12 promotes this to stable with extremely minor changes. We will add support for the stable version when it makes sense to do so.
