service/sockets: Implement network services for new firmware versions

This commit implements various network services required for newer firmware
versions. Key changes include:

- Add bsd:nu service for firmware 15.0.0+ with proper event handling
- Add bsdcfg implementation with complete interface declarations
- Add dns:priv and ethc (c/i) services
- Register all new services in the service manager
- Extend BSD implementation with additional socket operations
- Remove room_network instance variable in favor of system.GetRoomNetwork()
- Fix kernel event creation by using ServiceContext in all appropriate places
- Update build system to include new source files
