pythongh-111698: Restrict Py_mod_multiple_interpreters to 3.12+ Under Py_LIMITED_API (pythongh-111707)

ericsnowcurrently · miss-islington · commit 978fb85ad87a · 2023-11-06T16:35:05.000Z
This should have been done in pythongh-104148. (A similar fix has already be done for that slot's value macros, and backported to 3.12. See pythongh-110968.) (cherry picked from commit 836e0a7) Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>
