Enable iOS navigation UI and simulator support

Adds NavigationUIEnabledPreference.automatic to GoogleMapsNavigationView
for proper turn-by-turn navigation display on iOS. Enables navigation
header, footer, and trip progress bar. Adds simulation mode for iOS
Simulator testing with location updates along the route.
