Title: core: Collection.destroy() should cleanup allItems, sorters and filters

Labels: core, refactoring, ai

Body: The current implementation of Collection.destroy() only clears _items and map. It should also:

1. Destroy allItems if it exists.
2. Destroy sorters and filters instances if they exist (they are typically instances of Neo.collection.Sorter and Neo.collection.Filter).

Proposed change:

    /**
     * Clears the map & items array before the super call
     */
    destroy() {
        let me = this;

        me.allItems?.destroy();

        me.filters?.forEach(item => {
            if (item.destroy) {
                item.destroy()
            }
        });

        me.sorters?.forEach(item => {
             if (item.destroy) {
                item.destroy()
            }
        });

        me._items.splice(0, me._items.length);
        me.map.clear();

        super.destroy()
    }
