wayland: initial support for showing the desktop

* Wayland: Support rendering the desktop

*Wayland support is optional via the --enable-wayland option

* eel-editable-label-c: remove unused variable

This was leftover from earlier code compatable only with x11

* Fix gtk-layer-shell-0 version check, improve error message when Wayland requested but not found
