[Maps] Move tooltips to store (#32333) (#32608)
Browse files Browse the repository at this point in the history
This is an internal refactor:
- move tooltip management out of layers, and to the mapbox-component
- use global handler iso of multiple handlers on individual layers (this did remove the cursor-pointer change, since we no longer are explicitly handling on-enter/leave events).
- put tooltip state in store

Fixes bugs:
- when layer is removed, any corresponding tooltip should be removed as well
- when layer is made invisible, any corresponding tooltip should be removed as well
