CarPlayNavigationViewController and RouteController should share location manager

[1ec5]

CarPlayNavigationViewController and RouteController own two independent location managers. NavigationService doesn’t have the ability to respond to two different location managers at the same time, so #3393 has to keep the two location managers in sync, selectively shielding one from notifications meant for the other. CarPlayNavigationViewController should share a location manager with RouteController, just like the two classes share a NavigationService.
