gh-93442: Make C++ version of _Py_CAST work with 0/NULL. (#93500)
Add C++ overloads for _Py_CAST_impl() to handle 0/NULL.  This will allow
C++ extensions that pass 0 or NULL to macros using _Py_CAST() to
continue to compile.  Without this, you get an error like:

    invalid ‘static_cast’ from type ‘int’ to type ‘_object*’

The modern way to use a NULL value in C++ is to use nullptr.  However,
we want to not break extensions that do things the old way.

gh-91320: Fix more old-style cast warnings in C++ (#93285)
Use _PyObject_CAST() in the public C API to fix C++ compiler
warnings: "use of old-style cast" (clang -Wold-style-cast).

bpo-40514: Drop EXPERIMENTAL_ISOLATED_SUBINTERPRETERS (gh-93185)
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

gh-60074: add new stable API function PyType_FromMetaclass (GH-93012)
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.

gh-93202: Always use %zd printf formatter (#93201)
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* Remove outdated notes about the %zd format in PyBytes_FromFormat()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.

gh-85858: Remove PyUnicode_InternImmortal() function (#92579)
Remove the PyUnicode_InternImmortal() function and the
SSTATE_INTERNED_IMMORTAL macro.

The PyUnicode_InternImmortal() function is still exported in the
stable ABI. The function is removed from the API.

PyASCIIObject.state.interned size is now a single bit, rather than 2
bits.

Keep SSTATE_NOT_INTERNED and SSTATE_INTERNED_MORTAL macros for
backward compatibility, but no longer use them internally since the
interned member is now a single bit and so can only have two values
(interned or not interned).

Update stats of _PyUnicode_ClearInterned().

C API. The token.h header file was only designed to be used by Python

Move Include/token.h to Include/internal/pycore_token.h. Including
this header file now requires that the Py_BUILD_CORE macro is
defined. It no longer checks for the Py_LIMITED_API macro.

* PyToken_OneChar() => _PyToken_OneChar()
* PyToken_TwoChars() => _PyToken_TwoChars()
* PyToken_ThreeChars() => _PyToken_ThreeChars()
