remote-desktop/session: Added boiler plate for clipboard integration
Nothing is hooked up, it only does basic sanity checking i.e. whether the clipboard was enabled when interacting with it. No actual clipboard integration is hooked up yet. This also syncs org.gnome.Mutter.RemoteDesktop.xml from gnome-remote-desktop. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1552>
