I'll be adding a value to indicate support for per-interpreter GIL in pythongh-99114.

…MITED_API (gh-111707)

This should have been done in gh-104148.

(A similar fix has already be done for that slot's value macros, and backported to 3.12.  See gh-110968.)

… Py_LIMITED_API (pythongh-111707)

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.)

This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.

PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.

A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).
