[Rev 01] RFR: 8245499: Text input controls should show handles on iOS

[Jose Pereda]

> After JDK-8242167, a JavaFX control is used for text input on iOS instead of the native control, on a touch enabled
> device. However, selection handles are not enabled and currently text selection is not possible at all.
> This PR enables handles on iOS as in the rest of the platforms with touch support.
> 
> It also tries to accommodate its style to the native style for handles, where selection handles have a circle shape and
> are a little bit bigger, and there is no caret handle.
