cxx: Add _get_wref() convenience to all classes 

This allows constructs like:

  auto w_obj = obj._get_wref();
  auto cb = std::bind([w_obj]() {
    auto o = w_obj.lock();
    if (!o) return;
    o->call();
  });
  event_add(..., obj, cb);

Note: I don't like how those wref work. Close to c++ wref but far from
EFL wref.
