Sergey MiryanovandNeil Schemenauer eda53e6cf1 [3.13] GH-91636: Clear weakrefs created by finalizers. (GH-136401) (GH-144214) 
Weakrefs to unreachable garbage that are created during running of
finalizers need to be cleared.  This avoids exposing objects that
have `tp_clear` called on them to Python-level code.
(cherry picked from commit b6b99bf7f1)
