bpo-36763: Use _PyCoreConfig_InitPythonConfig() (GH-13398)

Browse source 
_PyPreConfig_InitPythonConfig() and _PyCoreConfig_InitPythonConfig()
no longer inherit their values from global configuration variables.

Changes:

* _PyPreCmdline_Read() now ignores -X dev and PYTHONDEVMODE
  if dev_mode is already set.
* Inline _PyPreConfig_INIT macro into _PyPreConfig_Init() function.
* Inline _PyCoreConfig_INIT macro into _PyCoreConfig_Init() function.
* Replace _PyCoreConfig_Init() with _PyCoreConfig_InitPythonConfig()
  in most tests of _testembed.c.
* Replace _PyCoreConfig_Init() with _PyCoreConfig_InitIsolatedConfig()
  in _freeze_importlib.c.
* Move some initialization functions from the internal
  to the private API.
