RangeSlider: add valueAt() function
This is necessary to e.g. show up-to-date values in tooltips for each
handle when live is set to false. It's copied from Slider.
[ChangeLog][Controls][RangeSlider] Added a valueAt() function to allow
accessing each handle's value when the live property is set to false.
