Remove QHashDummyNode and avoid undifined behavior
A lot of code in QHash is doing casting to QHashNode while the pointer may be of type QHashDummyNode. This is a lot of undefined behavior. Remove QHashDummyNode and specialize QHashNode for QHashDummyValue instead. QHashDummyValue is the only type for which QTypeInfo::isDummy is true. Q_DUMMY and QTypeInfo::isDummy are internal API, so is QHashDummyNode, so we can remove them.
