gh-135953: Reduce memory usage of stack collectors (#138875) The stack collector base class keeps all frames until export() is called, which causes significant unnecessary memory usage. Instead, we can process the frames on the fly in the collect call by dispatching the aggregation logic to the subclass through the process_frames method.
