The function xwl_output_remove() is called when removing a monitor, but
the actual status of the RandR output does not change.
So, when RRTellChanged() is called from update_screen_size(), it won't
have the output connection status up to date in the RandR event
RROutputChangeNotifyEvent and X11 applications relying on that event
like Qt will fail to emit their signal QGuiApplication::screenRemoved.
To avoid that issue, make sure to mark the RandR output as disconnected
prior to call xwl_output_remove().
Fix commit 204f10c29 ("xwayland: Call RRTellChanged if the RandR configuration may have changed")
