Description: We do two things here: immortalize the builtin structseq types, and immortalize tp_dict, tp_bases, and tp_mro for builtin types. This is necessary for a per-interpreter GIL. Note that we could also take the approach to immortalization that no immortal object should ever be freed, even if allocated dynamically. That's something we'll sort out as soon as we can. In the meantime, the change here takes care of isolation concerns. Issue: gh-84436
