Get rid of QQmlVMEMetaData

It is unused now and we can remove it as well as its QByteArray based storage.
The non-emptyness of the meta-data QByteArray was also used to indicate whether
it is necessary to create a VME meta-object when instantiating an object. This
bit is now folded into the flag of the QFlagPointer storing the property
caches.
