simplified fullscreen and orientation handling

- iPad: rotate to device orientation on startup
- fixed controls in portrait fullscreen
- iOS: don’t call setNeedsDrawing multiple times
- On iOS we call set needs drawing only once.
- Added cooldown time to MPV.Client setNeedsDrawing to avoid multiple successive calls
- make fullscreen animation smoother
- dragGesture now calls toggleFullScreenAction
- fix tvOS and macOS build
