Persist user rotations of external displays.
It also introduces a command line tool to rotate external displays for
testing purposes.
Instead of changing signatures of freezeRotation(), thawRotation() and
isRotationFrozen(), introduce 3 new methods to IWindowManager interface.
The old methods are being used pervasively.
Also resolved some style issues in DisplaySettings class.

Test: Rotation locks via settings still work. User rotation mode and
user rotation values for external devices are persisted as expected in
storage. DisplaySettingsTests passes.
