* bpo-42272: improve message/module warning filter docs

"The Warnings Filter" section of the warnings module documentation
describes the message and module filters as "a string containing a
regular expression".  While that is true when they are arguments to the
filterwarnings function, it is not true when they appear in -W or
$PYTHONWARNINGS where they are matched literally (after stripping any
starting/ending whitespace).  Update the documentation to note when they
are matched literally.  Also clarify that module matches the
"fully-qualified module name", rather than "module name" which is
ambiguous.

* bpo-42272: remove bad submodule warning filter doc

The `error:::mymodule[.*]` example in the "Describing Warning Filters"
section of the warnings module documentation does not behave as the
comment describes.  Since the module portion of the filter string is
interpreted literally, it would match a module with a fully-qualified
name that is literally `mymodule[.*]`.

Unfortunately, there is not a way to match '"module" and any subpackages
of "mymodule"' as documented, since the module part of a filter string
is matched literally.  Instead, update the filter and comment to match
only "mymodule".

This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing:

* the configure option
* the macro
* the code enabled by the macro

…ibility (GH-93302)

In previous versions of Python if an IntEnum member was combined with another integer type value using a bit-wise operation, the resulting value would still be the IntEnum type.  This change restores that behavior.

This is a rework of #5774 on current main. I was a bit more
conservative in making changes than the original PR.

See @csabella's comments on issue #77024 and the discussion
on #5774 for explanations of several of the changes.

Added a new stable API function ``PyType_FromMetaclass``, which mirrors
the behavior of ``PyType_FromModuleAndSpec`` except that it takes an
additional metaclass argument. This is, e.g., useful for language
binding tools that need to store additional information in the type
object.
