Introduce an OVERRIDE_MIN_ASPECT_RATIO_PORTRAIT_ONLY change ID

This change ID will determine whether the OVERRIDE_MIN_ASPECT_RATIO override will be applied for portrait only activities (if enabled), and for all orientations (if disable).

Note that this change is enabled by default because it will need to be
enabled for most use cases.
