Title: Fixes BHV-14524 and ENYO-247

## Issue
Tooltips can linger if the focus is programmatically changed or via 5-way from disabled activators

## Fix
Adds a singleton tooltip observer that is notified when a tooltip is display or spotlight focus changes and requests the currently displayed tooltip (if any) be hidden

## Notes
This reverts #1609 with an alternate solution
