Separate natural display orientation for configuration

The usages of getNaturalOrientation in DisplayRotationCompatPolicy
assumes that the orientation is based on the logical display size
without considering insets.

For example,
Logical display size 2076x2152=portrait

If the navigation bar occupies height 146.
Then the available size for app is 2076x2006=landscape
