Summary: Withf013a4369c,cd6b69a4d2,d960be4b3fandedb200f6bcall possible backends of a Wayland session have been ported to using the internal functions of AbstractWaylandOutput's for managing outputs. This removes the alternative code path used before in these backends, what simplifies the code and is also a prerequisite to removing the Screens global in the future.
