Add MustIncludeAdditionalItemPVCs to help track BIA added PVC's PVB creation. (#10501)

* Add MustIncludeAdditionalItemPVCs structure in backup. It's used to track PVCs returned by BIA with mustIncluded annotaion and PVC is excluded from backup by global filter.
* Modfiy the volumeHelper interface to add a parameter function for ShouldPerformFSBackup.
* Modify to support fine-grained backup filters.
* Modify according to comments. Use a read-only interface to replace the parameter function.
