migration user setting to VM notificationchannel
- move voicemailNotificationSettingsUtil from package/service/telephony
to framework/opt/telephony/util so that it can be referenced by
notificationChannelController
- voicemail notification user preference was based on subId but
notification channel don't differentiate subId. simply read the
default subId from preference and migrate if there is a match.
