Partial fix for 32862

- added overloads to certain methods to allow null as a default parameter which more closely mimics CPython's behavior - added return of 'default' values to some functions that matches CPython behavior. - this fix improves the test_unicodedata.py passing rate as well. Fix whitespace changes
