[issue37526] Add support.catch_threading_exception()

[STINNER Victor]

STINNER Victor  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.

See also bpo-36829: Add test.support.catch_unraisable_exception().

catch_threading_exception() is very close to catch_unraisable_exception().

[issue37526] Add support.catch_threading_exception()

[STINNER Victor]

New submission from STINNER Victor :

bpo-1230540 added threading.excepthook() to handle "uncaught exceptions raised 
by Thread.run()".

I propose to add support.catch_threading_exception(): context manager to ease 
catching these exceptions.

Attached PR implements it.
