Move pvc annotation removal from CSI RIA to regular PVC RIA

[sseago]

Combine existing PVC non-CSI RIAs and move annotation removal out of the CSI plugin to fix issues with
CSI volumes when using fs-backup

Thank you for contributing to Velero!

Please add a summary of your change

The CSI RIA plugin removed several annotations on restore. Because the CSI plugin exits early without action when not restoring via CSI snapshot or datamover, these annotations were not removed when CSI volumes were restored via fs-backup. For the linked issue, this meant that restoring to a cluster with a different CSI driver would fail when using fs-backup. These annotations should always be removed, not just when using CSI snapshots, so this code needed to be moved to a regular RIA that runs in all cases.

There were already two non-CSI RIA plugins for PVCs. Rather than create a third one, this PR combines those into one, to avoid needing 3 different grpc calls -- the CSI plugin remains separate.

Because the non-CSI plugin already handled selected node in a more targeted way (already documented process for explicit node change via configmap, and if there is no configmap and the selected node does not exist in restore cluster, then the annotation is removed), the migrated annotation removal functionality no longer applies to the selected node, so now the behavior will match documented behavior in all cases.

Could perhaps add a comment in this file that more generic actions to make PVC restore successful are in ../pvc_action.go
