Deno.listen w/ unix transport on Windows

[Hexagon]

Not sure if this is supposed to work or not, but I'll give it a shot:

const listener = Deno.listen({ 
    path: "c:\\temp\\my.sock",
    transport: "unix"
});

listener.close()

error: Uncaught TypeError: ops.op_net_listen_unix is not a function

(Windows 10)

Supporting Unix sockets on Windows would depend on tokio-rs/mio#1610 I think. Right now you are getting the error because the relevant code is Unix-only and not compiled on Windows.

Good news!
Rust libs team has accepted Windows AF_UNIX implementation.
