Build fix.

* UIProcess/ios/forms/WKAirPlayRoutePicker.mm:
(-[WKAirPlayRoutePicker showAirPlayPickerIPad:fromRect:]): Cast the return value of
[getMPAudioVideoRoutingPopoverControllerClass() alloc] to resolve ambiguity about which
-initWithType: we are calling.
(-[WKAirPlayRoutePicker showAirPlayPickerIPhone:]): Cast to resolve ambiguity.
(-[WKAirPlayRoutePicker show:fromRect:]): Cast for consistency.
