bpo-44731: Simplify the union type implementation (GH-27318) 
Remove direct support of typing types in the C code because they are already supported by defining methods __or__ and __ror__ in the Python code.

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``.

bpo-42233: Correctly repr GenericAlias when used with typing module (GH-23081) 
Noticed by @serhiy-storchaka in the bpo.  `typing`'s types were not showing the parameterized generic. 
Eg. previously:
```python
>>> typing.Union[dict[str, float], list[int]]
'typing.Union[dict, list]'
```
Now:
```python
>>> typing.Union[dict[str, float], list[int]]
'typing.Union[dict[str, float], list[int]]'
```

bpo-41923: PEP 613: Add TypeAlias to typing module (#22532)

proper PEP 484-compliant type aliases from regular top-level variable
assignments.

bpo-38605: Make 'from __future__ import annotations' the default (GH-20434) 
The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions.

For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).
