Automatically register comparison operators in QMetaType

This removes the fully manual registration of comparison operators in
QMetaType and replaces it with an automatic registration through
Q_DECLARE_METATYPE().

[ChangeLog][QMetaType] The QMetaType::registerComparator() and
QMetaType::registerEqualsComparator() have been removed.
Q_DECLARE_METATYPE() now automatically registers any
operator==() and/or operator<() for a type visible where
it is used on that type, as part of declaring its meta-type.
