Andy Wickham 830e4b7ce0 Add long swipe from app to overview gesture (with flag). 
High level:
 - As you swipe up from an app (OtherActivityInputConsumer),
   a state transition animation to All Apps is created in
   AnimatorControllerWithResistance. The animation is played
   alongside the Recents resistance animation (i.e. past the
   settling point of Overview, which is at mCurrentShift 1).
 - The actual state transition to All Apps only happens if you
   release your finger in the "all apps region." This is set to
   mCurrentShift 2, so double the distance that Overview rests.
 - A haptic plays whenever you enter or exit this region, and
   the all apps animation is set to 0 until the region is
   active. This is so it's clear that something different is
   happening.
 - The panel that was previously used for tablets is now used
   for phones during this transition. It comes in at full
   opacity when you enter the region, and the contents (apps
   and search suggestions) fade in as you continue swiping.
 - The only gesture that is recognized in the all apps region
   is a fling downwards, which will return you to the previous
   app. Otherwise a left/right/up fling or slow release will
   finish the all apps transition.
 - The threshold is ignored if the flag is disabled (default)
   or if FallbackActivityInterface is active.

Flag:
The threshold is ignored if ENABLE_ALL_APPS_FROM_OVERVIEW is
disabled (default).

Bug: 259619990
Bug: 275132633
Test: Manual with and without the flag enabled
