gh-115816: Improve internal symbols API in optimizer (#116028)

- Any `sym_set_...` call that attempts to set conflicting information
  cause the symbol to become `bottom` (contradiction).
- All `sym_is...` and similar calls return false or NULL for `bottom`.
- Everything's tested.
- The tests still pass with `PYTHONUOPSOPTIMIZE=1`.
