QMetaObject: remove commented out normalizeTypeInternal() declaration

It is out-of-sync with the actual implementation in qmetaobject_moc_p.
we could change the parameter types, but it will only go out-of-sync
again if the implementation is changed in the future. So just remove the
whole comment.

Amends 9164609 and
4dbac23.

Pick-to: 6.9
