Create util for VoicemailProviderSetting operations.
This is mostly moving functionality from CallFeaturesSetting into a
utility class. I tried to tidy up some names/styling, but the logic
is unchanged.
These are essentially stand-alone functions which manipulate the
SharedPreferences for VoicemailProviderSettings. I considered adding
them as static methods on VoicemailProviderSettings, but since they
manipulate the storage of VoicemailProviderSettings at a different
level, it seemed like better organization to put them by themselves.
