Add provisioner-aware DataImportCron configuration via StorageProfile annotations

Add support for provisioner-specific requirements when creating snapshots
and PVCs for DataImportCron. Some provisioners have specific needs:

- GKE Persistent Disk requires snapshot-type: images parameter in VSC
- GKE Persistent Disk and Rook Ceph RBD require RWO access mode for DataImportCron PVCs

Change details:
- Add StorageProfile annotations for DataImportCron configuration:
    cdi.kubevirt.io/useReadWriteOnceForDataImportCron: Signals RWO access mode
    cdi.kubevirt.io/snapshotClassForDataImportCron: Specifies VSC name
- Centralize provisioner-specific configuration in storagecapabilities:
    UseReadWriteOnceForDataImportCronByProvisionerKey: Maps provisioners requiring RWO
    SnapshotClassParametersForDataImportCronByProvisionerKey: Maps provisioners to VSC parameters
- StorageProfile controller automatically reconciles annotations based on provisioner
- DataImportCron controller applies RWO from StorageProfile when DV doesn't specify access modes
- DataImportCron controller selects VSC with priority: StorageProfile annotation > StorageProfile status > standard selection
- Unit tests for both controllers
- Update documentation with annotation details
