Might be worth just making a LogPathArray::fromVec.
Also, while it's handled right here, I think we need to be very careful with Vec since drop could still be called and we'd have a use-after-free.

Adds two new APIs for our FFI to support catalog-managed tables:
snapshot_with_log_tailto get the latest snapshot of a catalog-managed tablesnapshot_at_version_with_log_tailto get the snapshot of a catalog-managed table at a specific versionAnd in order to implement the above, a new
LogPathArraytype is introduced to communicateVec<LogPath>across FFI (basically just uses ptr + len for the array type and theFfiLogPathdoes KernelStringSlice + size + mod time)The above APIs are behind a new
catalog-managed(FFI) feature flag similar to kernel's owncatalog-managedflag.How was this change tested?
