gh-107249: Implement Py_UNUSED() for MSVC (#107250) Fix warnings C4100 in Py_UNUSED() when Python is built with "cl /W4". Example with this function included by Python.h: static inline unsigned int PyUnicode_IS_READY(PyObject* Py_UNUSED(op)) { return 1; } Without this change, building a C program with "cl /W4" which just includes Python.h emits the warning: Include\cpython/unicodeobject.h(199): warning C4100: '_unused_op': unreferenced formal parameter This change fix this warning.
