Use bigger task size in app to overview carousel

- Introduced carouselTaskSize that represent size of TaskView in app to overview carousel, that is bigger than size of TaskView in Overview state
- Use nonGridScale and translation to scale TaskView to the desired carousel size
- For current task, inroduced carouselScale and translation to apply similar transformation at the carousel. They will be reset in `onPrepareGestureEndAnimation` after gesture is released and form the grid. Carousel translation can be invalidated and aniamte to 0.
- Fixed current task left/right wiggle that is caused by task shrinks and translate in different direction. Pivot is now moved to top right (or top left for RTL), to align with movement of current task.
- To compensate for the pivot change, current task is translated back to the carousel position by taskTranslation, and again translated by carouselTranslation for carousel -> fullScreen scaling. A complex interpolator is introduced to make current task moves in a vertical straight line rather than a curve.
- Fixed a bug in AnimatorControllerWithResistance when scaleStartResist==scaleMaxResist that causes division by 0. For grid overview, resistance kicks in after reaching carousel size, and current task size won't reduce further
- Added PendingAnimation#addAnimatedFloat that uses animator provided by AnimatedFloat, so the animator can be canceled and reaniamte from AnimatedFloat side; AnimatedFloat now clears the property values during cancel so the canceled animator still referenced by PendingAnimation can no longer change the values
