gh-98724: Fix Py_CLEAR() macro side effects (#99100) (#99288)
The Py_CLEAR(), Py_SETREF() and Py_XSETREF() macros now only evaluate
their argument once. If an argument has side effects, these side
effects are no longer duplicated.

Add test_py_clear() and test_py_setref() unit tests to _testcapi.

The Python C API
================

The C API is divided into three sections:

1. ``Include/``: Limited API
2. ``Include/cpython/``: CPython implementation details
3. ``Include/internal/``: The internal API

Information on changing the C API is available `in the developer guide`_
