Replace QmlList* and QList* support with a single QmlListProperty type

As a value type QmlListProperty doesn't consume any memory in the object.
It also has a companion QmlListReference class that is part of the public
API for C++ developers to interact with that also manages memory issues
that existed with previous solutions (if the containing QObject was
destroyed it left a dangling pointer).
