xdgshell: Tell the compositor the screen we're expecting to fill

Browse Source 
The xdgshell protocol allows us to tell the output to fill. This makes
it possible to use fullscreen confidently on systems with multiple
screens knowing that our windows won't be overlapping one another by
calling setScreen accordingly before QWindow::showFullScreen.

Pick-to: 6.1 6.0 5.15
