QMetaType: don't create a registry just to query its emptiness
The function-call operator of QGlobalStatic creates the payload object
unless is has already been deleted. When performing read-only
operations on the payload object, it's better to use
QGlobalStatic::exists() + the dereference operator instead, because
that prevents the creation of the payload just to find it empty.
Pick-to: 6.3
