/// Create a new UDP socket.
///
/// Similar to `socket(AF_INET or AF_INET6, SOCK_DGRAM, IPPROTO_UDP)` in POSIX.
/// On IPv6 sockets, IPV6_V6ONLY is enabled by default and can't be configured otherwise.
///
/// This function does not require a network capability handle. This is considered to be safe because
/// at time of creation, the socket is not bound to any `network` yet. Up to the moment `bind` is called,
/// the socket is effectively an in-memory configuration object, unable to communicate with the outside world.
///
/// All sockets are non-blocking. Use the wasi-poll interface to block on asynchronous operations.
///
/// # Typical errors
/// - `not-supported`: The specified `address-family` is not supported. (EAFNOSUPPORT)
/// - `new-socket-limit`: The new socket resource could not be created because of a system limit. (EMFILE, ENFILE)
///
