hs-v3: Add the helper function mark_conn_as_waiting_for_circuit

This helper function marks an entry connection as pending for a circuit and
changes its state to AP_CONN_STATE_CIRCUIT_WAIT. The timestamps are set to
now() so it can be considered as new.

No behaviour change, this helper function will be used in next commit.

Part of #28669
