Move adding views logic to privateProfileManager

- Have the animation happen according to the state of private space.
- Have the transition happen only once by setting the current transition to null at the end of transition and by ensuring
where the transitions are allowed.
- Removing controller class.

- The onClick controls the enablement of the profile. On reset (when getting the transition) is what controls the animation
during expand.

tldr- In the collapse case:  execute() is called -> animation happens  -> addPsHeader
tldr- Expand case: post() is called -> addPsHeader -> animation happens.

Collapse:
onClick() -> AACV.onAppsUpdated() that resets & apply/RUNS runnable because EXECUTE
-> AAList.onAppsUpdated() (which is called at the same time animating happens which we should cancel and do at end callback)
-> AAList.onAppsUpdated() gets called again

Expand:
onCLick() -> AACV.onAppsUpdated() that resets & apply runnable
-> AAList.onAppsUpdated() (no animation running)
-> AAList.onAppsUpdated() (no animation running)
-> addPrivateSpaceHeader
-> then unlockAction() runnable because its posted at this point
