QMetaType: disallow automatic registration of reference type
The automatic registration code that would be added will break
with a reference type.
QObject's template code calls QMetaTypeId2 on the arguments of the
signal. Including on references.
Reference type cannot be register as metatype. They are not supported
in QVariant, or in QueuedConnection.
