fn find_slot_meta_in_cached_state<'a>(
    working_set: &'a HashMap<u64, SlotMetaWorkingSetEntry>,
    chained_slots: &'a HashMap<u64, Rc<RefCell<SlotMeta>>>,
    slot: Slot
) -> Option<Rc<RefCell<SlotMeta>>>

Returns the SlotMeta of the specified slot from the two cached states: working_set and chained_slots. If both contain the SlotMeta, then the latest one from the working_set will be returned.
