bpo-34170: Add Python/coreconfig.c for _PyCoreConfig (GH-8607)
* Add Include/coreconfig.h * Move config_*() and _PyCoreConfig_*() functions from Modules/main.c to a new Python/coreconfig.c file. * Inline _Py_ReadHashSeed() into config_init_hash_seed() * Move global configuration variables to coreconfig.c
