Tune springs when app animates home into the hotseat on devices

with a taskbar.

Thought about using the Builder pattern here but the CL becomes
much larger due to SwipePipToHomeAnimator having its own
Builder.

Bug: 268026344
Test: swipe up to close app thats in hotseat
      swipe back to close app thats in hotseat
