[iOS] Always show data counts in CBDCollectionView

- iOS Clear Browsing Data CollectionView
- It was among the goals of the new Clear Browsing Data UI (behind the new-clear-browsing-data-ui flag) to show the browsing data counting results in each entry's detail text label, depending on the selection state of an item.
- This change carries out the current plan, which is to show data counts regardless of the selection states (still behind the flag).
