Add onCarrierRoamingNtnEligibleStateChanged callback. 

Mark a phone object as carrier roaming ntn eligible if:
- Phone supports P2P SMS over satellite
- Device is not connected to Wi-Fi
- Phone is OUT_OF_SERVICE

Moved isCellularAvailable() from SatelliteSOSMessageRecommender to
SatelliteServiceUtils so that it can be used easily by other classes.
