Title: Only allow at most 1 vehicle interface to be active via the Enabler.

This is a rather large change with these primary goals:

* Instead of checkboxes, use a ListPreference so at most one VI type
can be selected at once in the Enabler.
* Only enable the data source preferences for each VI if that VI is
selected.
* Don't enable the USB source by default in the VehicleService
