Android Auto: make sorting-order of favorites configurable

[ntruchsess]

Describe the idea (required)

as a user of Android Auto I'd like to access favorites sorted by distance from the current position'.

Tell us about the expected behaviour (required)

in Android Auto currently the favorites within a given group of favorites are sorted by most-recently-modified.
While driving one often needs to navigate to locations that are close to the current position while access to locations far away might be less important. Therefore I'd like to be able to change the sorting-order of favorites to 'by distance from the current position' (like it is done with POIs from the map).

This is not just a usability-issue. In Android Auto the number of favorites that can be displayed in a given favorite-group is limited due to restrictions imposed by Google which currently results in the least-recently-modified favorites not being displayed as soon the number of favorites in that group exceeds the given limit. While driving one cannot re-group favorites and a favorite that is not displayed due to this limitation cannot be found by other means, even if it is close to the current position.

Tell us about alternatives you've considered (required)

1. add an action to the header of the FavoritesScreen that allows to change sort-order of favorites on-the-fly (this requires an update of androidx.car.app:app and androidx.car.app:app-projected from 1.2.0 to version :1.3.0-rc01 (1.2.0 is pretty outdated anyway...).

2. add a config-setting accessible via the Android-Auto settings screen that allows to change the sorting order in the existing favorite groups.
