Support Callback Negotiation Between Matching ALPNs

[ManickaP]

Describe the feature you'd like supported

When a new connection is accepted on the server side, we might want to do the final application protocol selection based on ClientHello SNI. Similar behavior is already supported via TLS over TCP for H/1.1 and H/2.

Original issue: dotnet/runtime#49423

Proposed solution

We would specify the complete list of supported ALPN when we start the listener and then we would narrow down the final ALPN when we set the configuration for the particular incoming connection.
