David Peter f1f3bd1cd3 [red-knot] Review remaining 'possibly unbound' call sites (#14284) ...

## Summary

- Emit diagnostics when looking up (possibly) unbound attributes
- More explicit test assertions for unbound symbols
- Review remaining call sites of `Symbol::ignore_possibly_unbound`. Most
of them are something like `builtins_symbol(self.db,
"Ellipsis").ignore_possibly_unbound().unwrap_or(Type::Unknown)` which
look okay to me, unless we want to emit additional diagnostics. There is
one additional case in enum literal handling, which has a TODO comment
anyway.

part of #14022
