python: Remove deprecated use of PyEval_ThreadsInitialized.

Browse Source 
The correct/modern way to do this is:

https://docs.python.org/3/c-api/init.html#releasing-the-gil-from-extension-code

PyEval_ThreadsInitialized was deprecated in 3.9 and will be removed
completely in 3.11, so we shouldn't use that function.
