Do not affect WindowContainer#getOrientation by animation

If an activity is launched with ActivityOptions#
makeSceneTransitionAnimation, it will invoke convertToTranslucent/
convertFromTranslucent to change mOccludesParent temporally for
showing shared elements above the previous activity.

And because WindowContainer#getOrientation() skips the requested
orientation if fillsParent() returns false. if fillsParent() uses
mOccludesParent, the activity may lose the orientation during the
transition which may cause unexpected display orientation change.
