Support Local Scene View with Compass and OverviewMap

[PaulAllanSturm]

Add support for Local Scene View to Compass and OverviewMap. This is mostly equivalent to the support for Scene View, but requires a separate code branch because LocalSceneView and SceneView don't have a shared ancestor with the common functionality.

For the example, I used the LocalSceneView code from the Sample Viewer.

The doc comments were updated to add LocalSceneView everywhere we had SceneView.

For OverviewMap, we had two constructors -- withMapView() and withSceneView(). It turns out that we don't even need separate constructors. I originally thought we did, because they require different "controller" types. But all the "controller" types subclass from GeoViewController, so they can all be treated as GeoViewController. So rather than creating a third constructor withLocalSceneView(), I just added an unnamed constructor that handles all three types. And then I marked the other two constructors "deprecated". We might want to discuss if that's the right approach.

Pull request overview

This PR adds support for ArcGISLocalSceneView to the Compass and OverviewMap widgets. Previously, these widgets only worked with ArcGISMapView and ArcGISSceneView. The key insight is that all three controller types inherit from GeoViewController, allowing a unified approach.

Key changes:

• Replaced type checks with switch statements on controller types for better pattern matching
• Consolidated OverviewMap constructors by deprecating withMapView() and withSceneView() in favor of a single unnamed constructor
• Added comprehensive documentation updates mentioning LocalSceneView alongside MapView and SceneView
