Bluetooth: Add support for PBAP UI preference

Usecase:
1) Connect with carkit that supports PBAP/MAP
2) Try to uncheck the checkbox for contact sharing from device sub
   settings menu

Expected Result:
1) DUT should display "Connected (No Media or Phone)"
1) Should be able to disconnect when checkbox moves from selected->unselected,
and carkit should be able to connect when checkbox is selected again

Observation:
1) No UI updates when PBAP/MAP are connected.
2) On unchecking Contact sharing checkbox nothing happens. PBAP connection
   remains active and user is not asked to disconnect profile level connection.

Fix:
Add support for PBAP UI preference in SettingsLib. Also Fix issues related to MAP
profile addition/removal.
Test: Connect from carkit, try disconnecting from sub settings menu by unchecking
Contact Sharing checkbox and check if PBAP is successfully disconnected.
