go/runtime: Rename port configuration in per-component networking

[gw0]

SUMMARY

Simple per-component networking support was implemented in https://github.com/oasisprotocol/oasis-core/pull/6123. Unfortunately, the chosen naming of ports is confusing and I would strongly suggest to:

• rename src_port to external_port (or host_port)
• rename dst_port to internal_port (or component_port, instance_port or machine_port)
