Python.h now also includes <string.h> in the limited C API version 3.11
and newer to fix the Py_CLEAR() macro which uses memcpy().
Add a Py_CLEAR() test in test_cext.
Modify also _Py_TYPEOF to use C23 typeof() if available.
Allow Py_LIMITED_API for (Py_GIL_DISABLED && _Py_OPAQUE_PYOBJECT)
API that's removed when _Py_OPAQUE_PYOBJECT is defined:
- PyObject_HEAD
- _PyObject_EXTRA_INIT
- PyObject_HEAD_INIT
- PyObject_VAR_HEAD
- struct _object (i.e. PyObject) (opaque)
- struct PyVarObject (opaque)
- Py_SIZE
- Py_SET_TYPE
- Py_SET_SIZE
- PyModuleDef_Base (opaque)
- PyModuleDef_HEAD_INIT
- PyModuleDef (opaque)
- _Py_IsImmortal
- _Py_IsStaticImmortal
Note that the `_Py_IsImmortal` removal (and a few other issues)
means _Py_OPAQUE_PYOBJECT only works with limited
API 3.14+ now.

Disable pedantic check for c++03 (unlimited API)
Also add a check for c++03 *limited* API, which passes in pedantic mode
after removing a comma in the `PySendResult` declaration, and allowing
`long long`.
On Windows in release mode, the test_cext and test_cppext can now
build C and C++ extensions.
* test_cext now also builds the C extension without options.
* test_cppext now also builds the C++ extension without options.
* Add C++14 test to test_cppext; C++11 is not supported by MSVC.
* Make setup_venv_with_pip_setuptools_wheel() quiet when
support.verbose is false. Only show stdout and stderr on failure.
