Add atomic recents animation while swiping up

State handlers can now specify atomic and non-atomic components of
their animations to states, which can be specified when creating a
new animation. There is now one atomic animation, when going from
NORMAL to OVERVIEW (and in reverse):
- RecentsViewStateController's animation (scale/alpha) is all atomic
- WorkspaceStateTransitionAnimation has atomic and non-atomic:
  - Hotseat and workspace alpha is atomic, as is workspace scale
  - Everything else (scrim, translation, qsb and drag handle alpha) is
    non-atomic
- All apps progress is non-atomic

Also simplified dragging through overview; no longer pulls against you,
so we use an OvershootInterpolator when flinging instead of our custom
interpolator for the spring effect.
