These types are either built-in or 'automatically declared' and so
don't need to be explicitly declared as metatypes.
In some cases, the type is required to be registered with the typedef
name, so those Q_DECLARE_METATYPE uses remain for now. In a future
patch we can also remove those and the typedefs themselves.
