[issue37526] Add support.catch_threading_exception()

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

Maybe the context manager could recreate attributes (set them to None) if the context manager is used wice, but I'm not sure that I don't want to promote to reuse catch_threading_exception().

I didn't check if catch_threading_exception() creates a ref cycle. I guess so. It's likely than storing an exception creates a ref cycle. Anyway, __exit__() removes attributes.
