#26368: Consider circuit isolation when closing redundant intro points

--------------------------+--------------------
When tor receives more than one request for connecting to an onion service
within a short amount of time, and these requests are circuit-isolated (by
sockauth, or something else), tor will launch multiple connections to an
intro point (one for each isolated request). When the first introduction
succeeds (intro acks), tor closes any circuits it considers redundant
(`rend_client_close_other_intros`). Tor should only close circuits if the
socks request isolation bits match.
