[Typechecker] Fix duplicate diagnostics when using attributes (#28888) * [Typechecker] resolveAttributedType() should invalidate the type repr after emitting a diagnostic, to prevent duplicate diagnostics later * [Test] Update '@noescape' attribute diagnostics * [Typechecker] Add a special diagnose method to TypeResolver that accepts a TypeRepr and invalidates it * [Typechecker] Rename the special 'diagnose' method to 'diagnoseInvalid' for clarity
