MINOR: quic: add reference to quic_conn in ssl context

Add a new member in ssl_sock_ctx structure to reference the quic_conn
instance if used in the QUIC stack. This member is initialized during
qc_conn_init().

This is needed to be able to access to the quic_conn without relying on
the connection instance. This commit is part of the rearchitecture of
xprt-quic layers and the separation between xprt and connection
instances.
