Adds APIs for Bluetooth PBAP and MAP access permission.

Currently, users' preference in phonebook and call history or message
access per each Bluetooth-paired device is stored in Settings application's
shared preferences.

However, some privileged applications other than Settings need to access
such data. So we decided to migrate the data from Settings application's
shared preferences to Bluetooth application's.
