DO NOT MERGE libcameraservice: Provide flag for overriding camera output to portrait.

Apps commonly do not handle landscape orientation cameras correctly. In
order to prevent stretching and rotation issues in these apps, this
patch adds a flag to override the behavior of these landscape cameras
to produce a portrait image instead by changing the SENSOR_ORIENTATION
reported by CameraCharacteristics and applying a 90 degree rotate and
crop.
