Add wireless display selection support to MediaRouter.
* Adds the new route type LIVE_VIDEO * Wireless displays support both LIVE_VIDEO and LIVE_AUDIO, making wireless display routes valid selections in when apps make selecting live audio routes available. * MediaRouter will only report/manipulate wireless displays that have already been paired at the system level.
