[3.15] gh-161185: Fix strict aliasing issue in Py_SETREF() macros family (#161186) (#161360) 
gh-161185: Fix strict aliasing issue in Py_SETREF() macros family (#161186)

Py_SETREF(), Py_XSETREF() and Py_CLEAR() now use memcpy() to set
_tmp_old_dst/_tmp_old_op to fix a strict aliasing issue.

Py_SETREF(), Py_XSETREF() and Py_CLEAR() now also cast
_tmp_old_dst/_tmp_old_op to PyObject* when calling
Py_DECREF()/Py_XDECREF() to avoid compiler warnings with the limited
C API.

Add the _Py_TESTCEXT_NO_TYPEOF macro to undefine the _Py_TYPEOF
macro.


(cherry picked from commit f8e65ee35d)
