Peek overview on motion pause, then animate fully on touch up

Add AnimationComponents.ATOMIC_OVERVIEW_PEEK_COMPONENT, and rename
previous ATOMIC_COMPONENT to ATOMIC_OVERVIEW_SCALE_COMPONENT.

When SWIPE_HOME is enabled:
- Overview lives to the left of Workspace, which is encoded in
  LauncherState.NORMAL.getOverviewScaleAndTranslation().
- Create atomic animation based on ATOMIC_OVERVIEW_PEEK_COMPONENT
  and OVERVIEW_PEEK state when swiping and holding from home screen.
