Fancy Zones - Titled Zones

### Description of the new feature / enhancement

I'd like if each Zone could have a title or notes that say what window goes there. I use a few zones that I swap through and forget where I wanted things to be.

### Scenario when this would be used?

Having 4 or 5 Zones that are titled so the user knows which window goes in which zone.

### Supporting information

_No response_

Start by locating the Fancy Zones implementation and its existing zone-layout and configuration entry points. Define how titles or notes should be entered, stored, and displayed for four or five zones, then verify that users can distinguish zones when switching layouts.
