gh-132657: Add maybe_enable_deferred_ref_count() (gh-142843) 
If we are specializing to `LOAD_GLOBAL_MODULE` or `LOAD_ATTR_MODULE`, try
to enable deferred reference counting for the value, if the object is owned by
a different thread.  This applies to the free-threaded build only and should
improve scaling of multi-threaded programs.
