/**
 * Macro must be used in the private section of `Class` and registers a
 * prefinalization callback `void Class::PreFinalizer()`. The callback is
 * invoked on garbage collection after the collector has found an object to be
 * dead.
 *
 * Callback properties:
 * - The callback is invoked before a possible destructor for the corresponding
 *   object.
 * - The callback may access the whole object graph, irrespective of whether
 *   objects are considered dead or alive.
 * - The callback is invoked on the same thread as the object was created on.
 *
 * Example:
 * \code
 * class WithPrefinalizer : public GarbageCollected<WithPrefinalizer> {
 *   CPPGC_USING_PRE_FINALIZER(WithPrefinalizer, Dispose);
 *
 *  public:
 *   void Trace(Visitor*) const {}
 *   void Dispose() { prefinalizer_called = true; }
 *   ~WithPrefinalizer() {
 *     // prefinalizer_called == true
 *   }
 *  private:
 *   bool prefinalizer_called = false;
 * };
 * \endcode
