[3/n] Pre-select fullscreen option if overridden

Settings > Apps > Aspect ratio (experimental)

Pre-select the fullscreen option if all are true:
- device manufacturer has overridden app to fullscreen
- app has not opted out of orientation override
- app has not opted out of user's fullscreen option
- user has not set any aspect ratio (USER_MIN_ASPECT_RATIO_UNSET)

"App default" will have a new value of USER_MIN_ASPECT_RATIO_APP_DEFAULT
if device manufacturer has overridden app to fullscreen, which will
behave the same as USER_MIN_ASPECT_RATIO_UNSET without the
device-applied fullscreen override.
