If Py_NOGIL is defined and Py_SET_REFCNT() is called with a reference
count larger than UINT32_MAX, make the object immortal.

Set _Py_IMMORTAL_REFCNT constant type to Py_ssize_t to fix the
following compiler warning:

Include/internal/pycore_global_objects_fini_generated.h:14:24:
warning: comparison of integers of different signs: 'Py_ssize_t'
(aka 'long') and 'unsigned int' [-Wsign-compare]

    if (Py_REFCNT(obj) < _Py_IMMORTAL_REFCNT) {
        ~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~
