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

Browse Source 
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
