C API: Restore removed PyEval_InitThreads() function #117929
Description
Since Python 3.7, PyEval_InitThreads() does nothing, since the GIL is now always created: https://vstinner.github.io/python37-gil-change.html This function is deprecated since Python 3.9 and I removed it in Python 3.13 alpha1.
Problem: my Fedora team identified that 16 projects are affected by this function removal.
- collectd
- freeradius
- gnumeric
- libesedb
- libsigrokdecode
- OpenIPMI
- openscap
- profanity
- pyliblo
- pyotherside
- python-confluent-kafka
- python-cradox
- python-gphoto2
- python-simpleaudio
- python-subvertpy
- rb_libtorrent
I propose to restore the function in Python 3.13 beta1, and remove it again in Python 3.14 alpha1.

collectd doesn't seem to be affected for 3 years: collectd/collectd@17d2fbe
The problem is that collected 5.12 is affected, there was no release since 2020. Only release candidates of a future 6.0 version.
