bpo-32030: Cleanup "path config" code (#4663)
* Rename PyPathConfig structure to _PyPathConfig and move it to Include/internal/pystate.h * Rename path_config to _Py_path_config * _PyPathConfig: Rename program_name field to program_full_path * Add assert(str != NULL); to _PyMem_RawWcsdup(), _PyMem_RawStrdup() and _PyMem_Strdup(). * Rename calculate_path() to pathconfig_global_init(). The function now does nothing if it's already initiallized.
