Martin Gräßlin 18939e17ed Move XRandrScreens to the x11/standalone plugin
By moving XRandrScreens the creation of screens gets simplified a lot
as there is no need to have windowing system specific init code. It all
just goes through the platform.

This also marks the point where the first X11 specific code is removed
from kwin_wayland.
