Migrate examples from `MapboxNavigationProvider` to `MapboxNavigationApp`

Nadie ha tomado este issue todavía.

It will be some time before we upgrade the examples repository to `com.mapbox.navigation:android:2.8.0-alpha.2`.

Opening so we can start considering the migration, but we're still building tools that make migration easier
For example the [extensions](https://github.com/mapbox/mapbox-navigation-android/blob/main/libnavigation-core/src/main/java/com/mapbox/navigation/core/internal/extensions/MapboxLifecycleExtensions.kt) are still experimental.

- [ ] ShowAlternativeRoutesActivity
- [ ] ShowManeuversActivity
- [ ] MultipleWayPointsActivity
- [ ] ShowTripProgressActivity
- [ ] ShowCameraTransitionsActivity
- [ ] ShowCurrentLocationActivity
- [ ] ShowJunctionsActivity
- [ ] FetchARouteActivity
- [ ] RenderRouteLineActivity
- [ ] TurnByTurnExperienceActivity
- [ ] MapboxSignboardActivity
- [ ] PlayVoiceInstructionsActivity
- [ ] ShowSpeedLimitActivity
- [ ] ReplayHistoryActivity
- [ ] CustomArrivalActivity
- [ ] ShowBuildingExtrusionsActivity

## Migration plan

We want to commit to a migration plan for the examples repository by **September 5th** because that is the week the `2.8.0` release becomes a release candidate and we will be committed to apis for a stable release.

Note that, not-migrating and using `MapboxNavigation` directly is also an option. `MapboxNavigationApp` is built for large apps.

## Resources

The architecture is designed for you to build de-coupled classes like the [LocationComponent](https://github.com/mapbox/mapbox-navigation-android/blob/d8d04fe75e53063f5e185c3779c04c7b0914f77d/libnavui-dropin/src/main/java/com/mapbox/navigation/dropin/component/location/LocationComponent.kt#L15-L39), or a more complicated example is the [CameraComponent](https://github.com/mapbox/mapbox-navigation-android/blob/d8d04fe75e53063f5e185c3779c04c7b0914f77d/libnavui-dropin/src/main/java/com/mapbox/navigation/dropin/component/camera/CameraComponent.kt#L32-L242). There are other approaches that are worth considering.

Some public documentation on the `MapboxNavigationApp` can be found here https://docs.mapbox.com/android/navigation/guides/androidauto/car-app-lifecycle/

We will also explore migration ideas in the [qa-test-app](https://github.com/mapbox/mapbox-navigation-android/tree/main/qa-test-app)

## Ideas are welcome

I'm obviously not the only one using this new library, so feel free to bring in some opinions and ideas. Feel free to open a pull request against this [migrate-MapboxNavigationApp](https://github.com/mapbox/mapbox-navigation-android-examples/pull/129) branch. Or create new pull requests.

Comienza con el plan de migración y las actividades de ejemplo enumeradas; después, revisa la documentación de MapboxNavigationApp y la qa-test-app en busca de patrones de migración. La rama migrate-MapboxNavigationApp y los recursos de arquitectura enlazados proporcionan contexto adicional. Se considera completado cuando se hayan migrado de forma coherente los ejemplos enumerados o se haya documentado la decisión de seguir usando MapboxNavigation directamente.
