bpo-38304: Add PyConfig.struct_size (GH-16451)
Add a new struct_size field to PyPreConfig and PyConfig structures to allow to modify these structures in the future without breaking the backward compatibility. * Replace private _config_version field with public struct_size field in PyPreConfig and PyConfig. * Public PyPreConfig_InitIsolatedConfig() and PyPreConfig_InitPythonConfig() return type becomes PyStatus, instead of void. * Internal _PyConfig_InitCompatConfig(), _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(), _PyPreConfig_InitFromPreConfig() return type becomes PyStatus, instead of void. * Remove _Py_CONFIG_VERSION * Update the Initialization Configuration documentation.
