Move final detection for Enum in checker.py #11984

Changes:

  • I've moved all final detection logic from semanal.py to checker.py. Why? Because we need type checking! For example, methods, properties, and other descriptors are not counted as Enum membres
  • We don't modify .is_final anymore. Why? It is too disruptive. Now this is a special-case for Enum only

Closes #11850

Thanks, looks good! It makes sense to do these checks during type checking. Left a few nits; feel to merge when you've addressed them (and fixed the merge conflict).
