Update example to have navigation info on android-auto and car-play

[bderrien]

This example includes an initial implementation of Android Auto / CarPlay support, without modifying the library

Summary:

• Display a 'waiting' view while there is no route
• On the map without guidance:
  • Display a button to view the itinerary
  • Display a button to recenter
  • Display a button to start navigation (with mobile app synchronization)
• In guidance mode:
  • Display a button to stop navigation (with mobile app synchronization)
  • Display step-by-step navigation info
  • Display trip estimation info
  • Display the route on the right side of the screen (Android only). On iOS, workaround by displaying the centered route but with bottom/top padding to avoid overlapping information banners

Waiting for:

• Branch 'support prompt visibility handling on Android Auto and CarPlay views' to be able to disable non-clickable prompts (iOS/Android)

Future improvements:

• On iOS, find a solution to manipulate the map, otherwise add left/right/up/down and +/- buttons to do so
• On iOS/Android, be able to click on alternative routes or at minimum disable the display of alternative routes on Auto
• Custom prompt display to properly show them on Auto
• Handle portrait mode (although I'm not sure it's very common in the market)
• Improve the design of information banners on iOS

Going even further:

• Allow map display without a route and enable route creation directly in Auto
