Submit visibility to the activities after the sleep state stable

ActivityRecord#shouldBeVisible can be affected by sleep status.
So in the original ensureActivityVisibility sequence:

beginActivityVisibilityUpdate
  ensureActivityVisibility =>
    ActivityRecord#shouldBeVisible =>
      commit visiblity to the activity if changed
endActivityVisibilityUpdate
KeyguardController#visibilitiesUpdated

Then if the occluding state has changed, execute above sequence again,
which could change the visibility again, so previous loop become
useless. Sometimes the loop cause issue like b/161036653.

An idea is to let KeyguardController to handle
TopActivityOccludesKeyguard and TopDismissingKeyguardActivity together
to update display sleep state. And only commit the visibility to
activities after sleep status is stable.

In this CL the ensureActivityVisibility sequence become
beginActivityVisibilityUpdate
  ensureActivityVisibility =>
    ActivityRecord#updateVisibilityStatus
endActivityVisibilityUpdate
KeyguardController#visibilitiesUpdated

if occluding state has changed, execute ensureActivityVisibility again.
Then after all sleep status has changed, commit the visibility to
activity.
