[python-ldap] Fix comments and suggestions from first review round
Backwards compatibility fixes (the majority of the changes): * Use Optional[<type>] instead of <type> | None * Use Union[<typeA>, <typeB>] instead of <typeA> | <typeB> * Remove use of from __future__ import annotations Other: * Move module from Lib/ldap_types.py to Lib/ldap/types.py * Remove use of from ldap_types import * * Move mypy.ini content to setup.cfg (pyproject.toml caused intermittent errors) * Extend tox.ini with mypy checks * Move _ldap.pyi to Lib/_ldap.pyi and add to MANIFEST.in * Add PEP561 type marker file (Lib/ldap/py.typed)
