bpo-40549: Convert posixmodule.c to multiphase init

Convert posixmodule.c ("posix" or "nt" module) to the multiphase initialization (PEP 489). * Create the module using PyModuleDef_Init(). * Create ScandirIteratorType and DirEntryType with the new PyType_FromModuleAndSpec() (PEP 573) * Get the module state from ScandirIteratorType and DirEntryType with the new PyType_GetModule() (PEP 573) * Pass module to functions which access the module state. * convert_sched_param() gets a new module parameter. It is now called directly since Argument Clinic doesn't support passing the module to an argument converter callback. * Remove _posixstate_global macro.
