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

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.

_posixsubprocess: add a static assertion to ensure that the pid_t
type is signed.

Replace _Py_IntegralTypeSigned() with _Py_IS_TYPE_SIGNED().

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.

* Add StrongRef class.
* Rename and reformat functions of the _Py_CAST() implementation.

Avoid _PyCodec_Lookup() and PyCodec_LookupError() for most common
built-in encodings and error handlers to avoid creating a temporary
Unicode string object, whereas these encodings and error handlers are
known to be valid.

The function was already deprecated in Python 3.11 since it calls
locale.getdefaultlocale() which was deprecated in Python 3.11.

* ``sys.executable`` is not set
* WASI does not support subprocess
* ``pwd`` module is not available
* WASI checks ``open`` syscall flags more strict, needs r, w, rw flag.
* ``umask`` is not available
* ``/dev/null`` may not be accessible

Python now always use the ``%zu`` and ``%zd`` printf formats to
format a size_t or Py_ssize_t number. Building Python 3.12 requires a
C11 compiler, so these printf formats are now always supported.

* PyObject_Print() and _PyObject_Dump() now use the printf %zd format
  to display an object reference count.
* Update PY_FORMAT_SIZE_T comment.
* Remove outdated notes about the %zd format in PyBytes_FromFormat()
  and PyUnicode_FromFormat() documentations.
* configure no longer checks for the %zd format and no longer defines
  PY_FORMAT_SIZE_T macro in pyconfig.h.
* pymacconfig.h no longer undefines PY_FORMAT_SIZE_T: macOS 10.4 is
  no longer supported. Python 3.12 now requires macOS 10.6 (Snow
  Leopard) or newer.
