bpo-46553: allow bare typing.ClassVar annotations (#30983)
These are used in the wild and covered by dataclasses unit tests.
Several static type checkers support this pattern.

bpo-44791: Fix substitution of ParamSpec in Concatenate with different parameter expressions (GH-27518)
* Substitution with a list of types returns now a tuple of types.
* Substitution with Concatenate returns now a Concatenate with
  concatenated lists of arguments.
* Substitution with Ellipsis is not supported.

bpo-46539: Pass status of special typeforms to forward references (GH-30926)
Previously this didn't matter because there weren't any valid code paths
that could trigger a type check with a special form, but after the bug
fix for `Annotated` wrapping special forms it's now possible to annotate
something like `Annotated['ClassVar[int]', (3, 4)]`. This change would
also be needed for proposed future changes, such as allowing `ClassVar`
and `Final` to nest each other in dataclasses.

bpo-46491: Allow Annotated on outside of Final/ClassVar (GH-30864)
We treat Annotated type arg as class-level annotation. This exempts it from checks against Final and ClassVar in order to allow using them in any nesting order.

message for too few/many arguments.

bpo-41249: Fix postponed annotations for TypedDict (GH-27017)
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-38291: Fix a spurious warning when using help(object) (#27039)
help(object) via pydoc.TextDoc.docclass(object) iterates over the
subclasses of object, which includes typing.io and typing.re if typing
is imported. It tries to access cls.__module__ for each of those
sub-classes. This change suppresses warnings when accessing
cls.__module__.

bpo-44098: Drop ParamSpec from most ``__parameters__`` in typing generics (GH-26013)
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``.
