[Remote Store] Use cluster default path type during snapshot restore

[ashking94]

Is your feature request related to a problem? Please describe

With optimised prefix pattern for remote store path (as mentioned in #12567), we would need to ensure that we associate remote store path type for an index which is being restored using snapshot restore. We will use the cluster setting cluster.remote_store.index.path.prefix.type for the newly restored index.

Describe the solution you'd like

We will hook the addition of customData in IndexMetadata in the snapshot restore path.

Describe alternatives you've considered

We have option to not associate any path type here, but this will prevent the user to use the best prefix strategy.
