[issue44117] [C API] Remove deprecated PyEval_InitThreads()

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

Remove PyEval_InitThreads() and PyEval_ThreadsInitialized() functions. The GIL is created by Py_Initialize() since Python 3.7, and so calling PyEval_InitThreads() explicitly was useless since Python 3.7. Deprecated in 3.9, PyEval_InitThreads() did nothing and PyEval_ThreadsInitialized() already returned true.
