Do not run rotation animation when folding/unfolding 

Disables screen freezing and rotation animation when
screen blocker is not removed (e.g. when folding or
unfoding a foldable device with two screens).

Fixes: 199897277
Test: manual fold/unfolds on foldable devices
Test: rotation animation works on inner/outer screen
