luci: sing-box 1.11.0 Migrate logic

This is just the secondary processing transition logic, and the source code will be modified in the future.

* Migrate WireGuard outbound to endpoint

* Migrate destination override fields to route options

* Migrate legacy inbound fields to rule actions

* Migrate legacy special outbounds to rule actions
