Fixes #4760 This commit make changes in 2 parts: 1) When a volumesnapshotcontent is persisted during backup, velero will reset its `Source` field to remove the VolumeHandle, so that the csi-snapshotter will not try to call `CreateSnapshot` when its synced to another cluster with a backup. 2) Make sure the referenced volumesnapshotclasses are persisted and synced with the backup, so that when the volumesnapshotcontent is deleted the storage snapshot is also removed.
