[iOS] Fix CBD Selection Anomaly after Font Change

Please refer to the bug for details.

-It's unclear how to instruct the table view to recover the selection
states for those previously selected cells after a reload triggered by
a font size change.
-We've previously (1596451) made changes so that
TableViewClearBrowsingDataItem's configureCell:withStyler: is again
solely responsible for a TableViewClearBrowsingDataCell's appearance.
-Therefore we turn back to the usual approach of not maintaining
a cell's selection state: maintaining states in items, reflecting
item states in cell appearances.
