  2. Move declaration to Include/cpython 

    That way it doesn't need the Py_LIMITED_API guard

  3. Initialize the memory 

    This is a further workaround: this time for the fact that
we can't rely on tp_alloc, which zeroes the memory (including
memory for subclasses, like slots in the test) for normal classes.

For the test type, this means the instances aren't initialized twice
(once in PyUnstable_Object_GC_NewWithExtraData, once again with
PyObject_Init after zeroing). Initializing twice throws off the global
refcount total in debug builds.
