Fix some issues with __round__ (#2907)

In python 3, add an overload for there being no digits argument
and make it return int.

In python 2, __round__ doesn't exist and SupportsRound doesn't exist
in the typing module. Use SupportsFloat for python 2 round().

Remove decimal's __round__ overload that takes None, since it doesn't exist
