Cancel unfold animation when rotation changes

In DeviceFoldStateProvider.kt, FOLD_UPDATE_FINISH_HALF_OPEN is emitted if the rotation changes while the animation is in progress.

 This targets the case when the device goes to tabletop mode during the transition.

+ Using RotationChangeProvider to fix problems when the new orientation change was received in a background thread unexpectedly. This fixes: (1) wrong launcher icons movement after the rotation, and (2) wrong dark overlay scrim after rotation.

+ Minor formattig fixes by ktfmt
