[issue34170] Py_Initialize(): computing path configuration must not have side effect (PEP 432)

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

Attached PR reworks _PyCoreConfig_Read() to leave _Py_path_config unchanged: *reading* the core configuration must not *modify* the path configuration.

The PR adds _PyCoreConfig.dll_path field.

The change is related to the PEP 432.
