volumes: rename existing volume resources

Rename `nomad_volume` to `nomad_csi_volume_registration` and
`nomad_external_volume` to `nomad_csi_volume` to better reflect their
intended use.

The deprecated top-level fields `access_mode` and `attachment_mode` were
not moved to the new resource.

The previous resources are now marked as deprecated.
