Using `NodePort` + `externalTrafficPolicy: Local` should set `Spec.Addresses` to only the nodes where Envoy is running

Description: When EnvoyProxy has type: NodePort:

  spec:
    provider:
      kubernetes:
        envoyService:
          externalTrafficPolicy: Local
          type: NodePort

all node addresses appear in Status.Addresses. But with externalTrafficPolicy: Local, the default, traffic is only routed to Envoy if it arrives at a node where there is a replica truly running. Only these addresses should appear in Status.Addresses

Repro steps: See above

Environment: Latest gateway version
