QOffscreenIntegration: Don't keep around removed screens 

The implementation of QOffscreenScreen::virtualSiblings() uses the list
of screens maintained in QOffscreenIntegration as input, so we need to
remove screens from this list as we remove them, to avoid treating
removed screens as siblings of still remaining screens.

While we're at it, remove the screens in reverse order, so that the
primary screen is the one removed last. This avoids having to update
the primary screen and move windows for each screen removed during
shutdown.
