_Py_DebugOffsets for PyLongObject are incorrect

[godlygeek]

Bug report

Bug description:

All other debug offsets are relative to the start of the object, but the offsets for PyLongObject's fields are relative to the start of an inner object, and so each field's value is too small by sizeof(PyObject).

CPython versions tested on:

3.13, CPython main branch

Operating systems tested on:

Linux
