_PyWeakref_ClearRef was previously exposed in the public C-API, although it begins with an underscore and is not documented. It's used by a few C-API extensions. There is currently no alternative public API that can replace its use. _PyWeakref_ClearWeakRefsExceptCallbacks is the only thread-safe way to use _PyWeakref_ClearRef in the free-threaded build. This exposes the C symbol, but does not make the API public. (cherry picked from commit db5af7d) Co-authored-by: Sam Gross <colesbury@gmail.com>
