/**
* 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
