[NUI] Add Selector constructor with SelectorChangedCallback internally (#1862)

To track property changes of Selector class, Selector constructor with
SelectorChangedCallback is added internally.

This is the same method applied to Color class.

By using this constructor, ColorSelector class also tracks property
changes internally.
