iOS: Associate UIScreen and show UIWindow on initial QWindow mapping

We delay showing the UIWindow until the first QWindow is created and
mapped to the screen. This allows external screens to stay in mirror
mode until a QWindow has been explicitly created on that screen. We
also remove the screen-association when the last QWindow on that
screen has been removed, which will return the external screen to
mirror mode.
