Non-serializable Properties

Stores must always be serializable, however sometimes you may want to persist a value on a store that can't be serialized. Values like these persist in the browser only when the application is resumed on the client.

When the application is paused, non-serializable properties are discarded.

Your task: Add a cleanup function in store.cleanup so that the stop button can clear the interval with clearInterval(). For that, add noSerialize import from '@builder.io/qwik' and use noSerialize function to wrap clearInterval function.
