Mapbox-gl-native: Hide the ℹ️ attribution button if map isn't interactive

[friedbunny]

When a map view has userInteractionEnabled=NO, the :information_source: button isn't tappable. It doesn't make much sense to have a non-tappable button, so we should hide it.

When there is no attribution button (or effectively none), we may also want to re-check for a telemetry opt-out.

Instead of just hiding the button, we should switch to text-only attribution in non-interactive maps.

For the textual attribution, most of https://github.com/mapbox/mapbox-gl-native/blob/2988ca16c1bfa8f00518411d2a711113fe88d13f/platform/macos/src/MGLMapView.mm#L364-L391 and https://github.com/mapbox/mapbox-gl-native/blob/2988ca16c1bfa8f00518411d2a711113fe88d13f/platform/macos/src/MGLMapView.mm#L427-L492 should port pretty straightforwardly to iOS.
