WIP: Implement panel title search logic

[kaydelaney]

After trying the behavior approach and finding critical limitations(PR), such as:

• Search by title when we had repeated panels did not work
• Saving dashboards that had a filter by title applied, removed the panels from the Dashboard JSON.

We have decided to take another chance with implementing the search logic in the scenes library.

This PR introduced new optional properties to SceneGridLayout, the idea is to use this feature toggles in the Grafana repository behind a feature toggle

  /** Panel search */
  showPanelSearch?: boolean;
  searchString?: string;
  panelsPerRow?: number;

Is there a way to build this as a behavior or / pluggable feature for the grid? (not sure if that is the case or if it's a good idea, but feels like a non core feature of the grid itself

I agree it really isn't a core feature. I'll try and see if I can think of a way to make it more "modular"
