Improve TV PiP menu buttons
- Save focused button when moving and changing orientation (e.g. during
expanded mode being toggled)
- Focus the first button when the menu is opened
- Makes sure all buttons are visibly reachable by setting the right
gravity based on orientation and whether all the buttons fit
- Scrolls to the focused button if it happens to go out of bounds during
any change
- Fade buttons out and in during orientation change
- Scale buttons to 1.1x when selected
- Fix move button description (typo in resource reference)
