QmlDesigner: Simplify InternalNode

Before we add new members the simple getter and setter without value are
removed because the model provides capsulation.

To  remove the weak pointer workaround std::enable_shared_from_this is
used which makes the class aware of its shared pointer. For that we
change to std::shared_ptr
