* Mostly value changes.
* Added a way to round the corners during swipe up to home animation.

* Tracks either the top or bottom of the rect for the fling/spring in the
Y direction.
- This allows us to have the icon always animate downwards.
* Scales the spring velocity for the Y component.

We did this already for mCurrentShift, which is used for all animations
except home animation. Now we do it for the home animation as well to
ensure we are properly cleaned up for the next interaction.
Test: Swipe up to home and double tap nav region before animation
finishes. Before, this would return to the app you swiped up from but
was in a broken state where subsequent swipes were ignored. Now we
jump to the home screen and remain there.

Now instead of an incorrect hack that simulated accelerating to the target,
we actually apply spring forces to make it feel realistic and work no matter
where the target is.
Added two helper classes for this:
- FlingSpringAnim handles the fling, applying friction until reaching the target,
then a spring to pull towards the final position (also applies if fling wasn't
in the right direction or strong enough to reach the target).
- RectFSpringAnim uses 2 FlingSpringAnims (x + y) to animate from a starting rect
to a target rect. It also has an animation to scale from the start rect to the
target rect, sending progress update callbacks to the caller.
