Update existing ECM settings to use new infrastructure

1. Update Notification Listener and A11y settings to call
   RestrictedLockUtilsInternal rather than checking appOp themselves

2. Rename ecm related methods to include Ecm rather than AppOp -
   implementation details are being moved to permissions module and may
   change.
