bpo-44606: Fix __instancecheck__ and __subclasscheck__ for the union type. (GH-27120) 
* Fix issubclass() for None.
  E.g. issubclass(type(None), int | None) returns now True.
* Fix issubclass() for virtual subclasses.
  E.g. issubclass(dict, int | collections.abc.Mapping) returns now True.
* Fix crash in isinstance() if the check for one of items raises exception.

bpo-44630: Fix assertion errors in csv module (GH-27127) 
Fix incorrect handling of exceptions when interpreting dialect objects in
the csv module. Not clearing exceptions between calls to
PyObject_GetAttrString() causes assertion failures in pydebug mode (or with
assertions enabled).

Add a minimal test that would've caught this (passing None as dialect, or
any object that isn't a csv.Dialect subclass, which the csv module allows
and caters to, even though it is not documented.) In pydebug mode, the test
triggers the assertion failure in the old code.

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-41486: zlib uses an UINT32_MAX sliding window for the output buffer (GH-26143) 
* zlib uses an UINT32_MAX sliding window for the output buffer

These funtions have an initial output buffer size parameter:
- zlib.decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE)
- zlib.Decompress.flush([length])

If the initial size > UINT32_MAX, use an UINT32_MAX sliding window, instead of clamping to UINT32_MAX.
Speed up when (the initial size == the actual size).

This fixes a memory consumption and copying performance regression in earlier 3.10 beta releases if someone used an output buffer larger than 4GiB with zlib.decompress.
