Correctly account for heap_pages_final_slots so it does not underflow
`rb_objspace_call_finalizer` creates zombies, but does not do the correct accounting (it should increment `heap_pages_final_slots` whenever it creates a zombie). When we do correct accounting, `heap_pages_final_slots` should never underflow (the check for underflow was introduced in 39725a4db6b121c7779b2b34f7da9d9339415a1c).
The implementation moves the accounting from the functions that call `make_zombie` into `make_zombie` itself, which reduces code duplication.
