Exposing NavigationMapView components

[Udumft]

Continuing after RouteMapViewController elimination, there are further topics to work on. This PR shaped several components (ArrivalController, CameraController, OrnamentsController and RouteLineController) which functionality could be exposed to users and further customisation.

Points to keep in mind for implementation:

• Decouple components from NavigationMapView or any other private dependency.
• Design configurable components behavior.
• Allow potential usage outside NavigationViewController.
• Re-use components in CarPlay
