[Android Auto] Remove direct MapboxNavigation references

[kmadsen]

All of the direct references to MapboxNavigation are to be deleted from the public api in favor of MapboxNavigationObserver or MapboxNavigationApp.current().

The MapboxNavigationApp did not exist during the original implementation, so only the most recent implementations are using the MapboxNavigationApp. This refactor will unlock the ability to disable and enable NavigationOptions at runtime.

When choosing to use MapboxNavigationObserver vs MapboxNavigationApp.current()

• Use MapboxNavigationObserver when registering for continuous data streams
• Use MapboxNavigationApp.current() for special cases, typically when a single is needed

Here is a list of classes that need to be migrated.

• CarNotificationInterceptor - already done, reference as a correct example
• CarAppLocation - already done, reference as a correct example
• MapboxCarNavigationManager - already done, reference as a correct example
• MainCarContext: MainActionStrip, MainCarScreen, MainScreenManager
• CarSpeedLimitRenderer [Android Auto] Remove MapboxNavigation from CarSpeedLimitRenderer #6325
• RoutePreviewCarContext, GeoDeeplinkNavigateAction [Android Auto] Remove MapboxNavigation from RoutePreviewCarContext #6226

• CarNavigationInfoObserver [Android Auto] Remove MapboxNavigation from CarNavigationInfoObserver constructor #6263
• CarLocationsOverviewCamera [Android Auto] Remove MapboxNavigation from CarLocationsOverviewCamera constructor #6225
• CarNavigationCamera [Android Auto] Remove MapboxNavigation from CarNavigationCamera and CarRouteLine #6219
• CarRouteLine [Android Auto] Remove MapboxNavigation from CarNavigationCamera and CarRouteLine #6219
• RoadLabelSurfaceLayer [Android Auto] Remove mapbox navigation from road name observer #6224
• RoadNameObserver [Android Auto] Remove mapbox navigation from road name observer #6224
• CarRouteRequest

Before refactoring this entirely, there should be consensus on this #6143
