Modify "Call Barring" UI to remove pref options per carrier

When KEY_CALL_BARRING_SUPPORTS_PASSWORD_CHANGE_BOOL or
KEY_CALL_BARRING_SUPPORTS_DEACTIVATE_ALL_BOOL are disabled, remove
the "Change Password" or "Deactivate Barring" preference, respectively.

Test: Modify CarrierConfig locally and verify corresponding UI is removed.
