MINOR: mux-quic: implement debug string for logs

Browse Source 
Implement MUX_SCTL_DBG_STR for QUIC MUX. This returns info for the
current QCS and QCC instances, reusing qmux_dump_qc{c,s}_info functions
already used for traces, and the connection flags.

This stream operation is useful for debug string sample support.
