QQmlMetaType: Clear property caches on qmlClearTypeRegistrations
Otherwise we may retain dangling pointers referencing invalid property
caches. Some metaobjects are created on the heap. If the memory manager
decides to re-use the heap space for new metaobjects, we can retrieve
the invalid property caches.
Pick-to: 6.5 6.4 6.2
Task-number: QTBUG-110933
