Add logs for all ExpandableNotificationRow transient views adding to and removing from NotificationStackScrollLayout

Add logs for all ExpandableNotificationRow transient views that are added to and removed from NotificationStackScrollLayout. To help with:
1. determining if the known additions and removals are working as intended (especially in a good order) .
2. discovering unknown additions and removals of transient rows.
