[3.8] bpo-37206: Unrepresentable default values no longer represented as None. (GH-13933) (GH-16141)
In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values
(like in the optional third parameter of getattr). "None" should be used if None is accepted
as argument and passing None has the same effect as not passing the argument at all.
(cherry picked from commit 279f44678c8b84a183f9eeb85e0b086228154497)
