Telephony: Add new api isMmsDataConnectivityPossible.

- Add a new telephony manager api to get possiblity of mms PDP.
- Its a preemptive API, if app is made aware of that MMS PDP is not possible
  then app can preempt the transaction. It would help in avoiding
  unnecessary PS ATTACH or DDS switches in msim devices.
