Calling `PyEval_InitThreads` has been deprecated in Python 3.7 and the function itself will be removed in Python 3.11. The current check guards this function behind a version check that only happens at compile time. This in turn leads to crashes when run on Python 3.6, as the necessary initialization for `PyEval_ReleaseThread` did not take place. This commit ensures the manual initialization takes place based on the runtime version of Python and avoids loading the associated symbols on Python 3.9 or later.
