Add a couple of socket examples that can be used with WAMR: - The `timeout_client` and `timeout_server` examples demonstrate socket send and receive timeouts using the socket options - The `multicast_client` and `multicast_server` examples demonstrate receiving multicast packets in WASM And add several macro controls for `socket_opts` example.
