ovn-sb.xml is missing three of the Port_Binding.types that have been
added: external, remote, and mirror. Document the ports types and what
they mean.
Fixes: b31c76000bef ("ovn: Support a new Logical_Switch_Port.type - 'external'")
Fixes: 74ada3273454 ("northd: Introduce the concept of transit routers.")
Fixes: 2a2fe266d09c ("northd: Added support for port mirroring in OVN overlay.")
