Compiled under MSVC 2019 with define EXPERIMENTAL_ISOLATED_SUBINTERPRETERS

Got compilation error of file Objects/unicodeobject.c at line 15931, about undefined variable "interned", it is function _PyUnicode_ClearInterned(), uncompilable code is "if (interned == NULL) {".

This happens because when EXPERIMENTAL_ISOLATED_SUBINTERPRETERS is defined then INTERNED_STRINGS is undefined hence global variable "static PyObject *interned = NULL;" is not created, and _PyUnicode_ClearInterned() uses this global variable "interned".

For reference attaching my version of "unicodeobject.c" which has compilation error at line 15931.

This build flag is experimental and unsupported. If you care, you should target Python 3.11 which is currently under development.
