Do not animate QSB and hotseat when portrait

Disables fold/unfold animation for QSB and hotseat
icons when in portrait orientation. Launcher workspace
icons and widgets are still animated intentionally.
Reuses NaturalOrientationRotationProvider which is currently
used to disable fold/unfold animation in the status bar when
in non-natural orientation.

Bug: 201518277
Test: fold/unfold on launcher in landscape =>
 QSB and hotseat animated;
 rotate screen during fold/unfold animation =>
 translation reset after rotating to portrait,
 animated after returning to landscape;
 rotate after fold/unfold animation => no changes
