Fix mypy: remove ParameterBaseKWArgs inheritance from ParameterKWArgs

ParameterKWArgs redeclares all ParameterBaseKWArgs fields so that
Sphinx can discover and document them. Mypy does not allow overwriting
TypedDict fields when extending, so the fix is to remove the
inheritance and have ParameterKWArgs be a standalone TypedDict that
includes all fields directly.
