Add realized_id attribute to nsxt_policy_transport_zone data source

This data source is replacing MP nsxt_transport_zone which is deprecated.
The nsxt_edge_transport_node resource requires this value, as it's not a policy resource and it is provided by nsxt_policy_transport_zone resource but not by the data source.
