Remove reference to NPVC

NotificationShadeWindowViewController will still exist in a scene based
System UI, so it cannot directly depend on NPVC. Unfortunately, this
required the addition of one method to SVC. Some of its other methods
have also been deprecated in this change, since they will not be called
with the scene container flag enabled.
