Add a custom gesture recognizer to trigger session disconnection when user swipe with a horizontal distance that exceeds half screen width, this works better in native-touch passthrough.

Original ios-moonlight triggers session disconnection with a short swipe from left edge, which happens frequently & unexpectedly in an intense native-touch passthrough gaming condition (like GenshinImpact).
