Support enable_commenter for instrument_connection (version 2)

[tammy-baylis-swi]

Description

Support enable_commenter for psycopg2/psycopg instrument_connection functions.

Fixes #3070

Depends on #4257 to fix instrument_connection in psycopg2 first. ✅

This replaces #3071. I've incorporated some feedback from that PR into this one.
