Introduce a new Home animation for workspace and the outgoing task.

The values are currently the same for all display and orientation
configurations, but they might change before launch.

There are a couple known imperfections:
* Swiping out of a hotseat app with very low velocity doesn't look
  great
* Sometimes, if the window movement reaches its final location faster
  than the background is done scaling, there is a small snap in icon
  position

Bug: 298089923
Flag: ACONFIG com.android.launcher3.enable_scaling_reveal_home_animation DISABLED
Test: verified with the flag on and off
