Remove nullOk parameter from Focus.of, FocusTraversalOrder.of, and FocusTraversalGroup.of (#68917) 

This removes the nullOk parameter from Focus.of, FocusTraversalOrder.of and FocusTraversalGroup.of, and creates maybeOf equivalents for each. The of methods now return non-nullable values, and the maybeOf equivalents return nullable values.
