bpo-41249: Fix postponed annotations for TypedDict (GH-27017) (#27204) 
This fixes TypedDict to work with get_type_hints and postponed evaluation of annotations across modules.

This is done by adding the module name to ForwardRef at the time the object is created and using that to resolve the globals during the evaluation.

bpo-44098: Drop ParamSpec from most ``__parameters__`` in typing generics (GH-26013) (#26091) 
Added two new attributes to ``_GenericAlias``:
* ``_typevar_types``, a single type or tuple of types indicating what types are treated as a ``TypeVar``. Used for ``isinstance`` checks.
* ``_paramspec_tvars ``, a boolean flag which guards special behavior for dealing with ``ParamSpec``. Setting it to ``True`` means this  class deals with ``ParamSpec``.
