[QUIC] Server side certificate selection via `ServerCertificateSelectionCallback` should work

[ManickaP]

ServerCertificateSelectionCallback. Used for SNI. Already used as part of setting the server certificate with a listener connection. Relevent: https://github.com/microsoft/msquic/blob/73bd4a7700b9d0c4f9570a46734eb9bf40f8448f/src/inc/msquic.h#L753

Apparently, this is supported by msquic, we should add support.
