gh-96478: Fix new test when run in refleak mode (#96615) 
./python.exe -m test -R : test.test_typing would fail, apparently
because the dictionary used in the @patch decorator was modified.

bpo-46642: Explicitly disallow subclassing of instaces of TypeVar, ParamSpec, etc (GH-31148) 
The existing test covering this case passed only incidentally. We
explicitly disallow doing this and add a proper error message.

gh-91621: Fix typing.get_type_hints for collections.abc.Callable (#91656) 
This mirrors logic in typing.get_args. The trickiness comes from how we

Documentation is intentionally omitted, so we can focus on getting the
runtime part in before the feature freeze.

gh-91243: Add typing.Required and NotRequired (PEP 655) (GH-32419) 
I talked to @davidfstr and I offered to implement the runtime part of PEP 655
to make sure we can get it in before the feature freeze. We're going to defer
the documentation to a separate PR, because it can wait until after the feature
freeze.

The runtime implementation conveniently already exists in typing-extensions,
so I largely copied that.

bpo-46581: Propagate private vars via _GenericAlias.copy_with (GH-31061) 
GH-26091 added the _typevar_types and _paramspec_tvars instance
variables to _GenericAlias. However, they were not propagated
consistently. This commit addresses the most prominent deficiency
identified in bpo-46581 (namely their absence from
_GenericAlias.copy_with), but there could be others.
