IPv6 on Windows not working correctly

[Leo-Besancon]

The TcpListener binding is not correctly configured for Windows edge-cases.
We should port the code from Bootstrap listener that has the correct behaviour (sets the needed flag with a socket2 socket:

socket.set_only_v6(false)?;

Right now, the bug probably means:

• That windows node runners with IPv4 should bind the protocol on IPv4 format in the config in order to be routable:

[protocol]
    bind = "0.0.0.0:31244"

• (Needs testing to be sure) Maybe routable windows node runners with IPv6 can only get INs from IPv6. Note: I don't seem to have trouble with this, but I'll wait for after genesis on mainnet to be sure, IN connections are few.
