gh-128954: Reorder _PyInterpreterFrame fields for reduced memory usage (#128958)

This reduces the size of _PyInterpreterFrame by 8 bytes on 64-bit
platforms using the free threading build due to alignment requirements.

This allows for slightly more recursive calls into the interpreter (from
C), but `test_call.test_super_deep` still crashes.
