XQuartz: Call RRScreenSizeNotify after handling externally-generated XP_EVENT_DISPLAY_CHANGED 

We get an XP_EVENT_DISPLAY_CHANGED event when our display configuration is
changed.  If this change was caused by hotplugging a monitor or Mac Display
Preferences changes by the user, we need to call RRScreenSizeNotify in order
to ensure new connections get the correct screen size.
