Give TcpListener.AcceptXAsync a CancellationToken

[JC3]

It would be great if TcpListener.AcceptSocketAsync and TcpListener.AcceptTcpClientAsync had overloads that took CancellationTokens.

What is the feasibility of this? I don't mind writing a proposal if I have to, I just am not familiar enough with .NET yet to write an effective one.

Trivial once Socket.AcceptAsync has an overload that supports cancellation, but while such an API has been approved, it's not yet implemented.

Oh! So it's pretty much, nothing to do but cross my fingers and wait, right?

This was actually just implemented for .NET 6 in #53340.
