Subject: Move propertyCache- and metaObject-related functions into
 QQmlMetaType

That's where the data resides. This allows us to lock the mutex only
once for all those methods, and it makes a large number of engine
pointers unnecessary.

Finally, we can now find the element type of a QQmlListProperty without
supplying an engine.
