fix(StatusRadioButton): StatusRadioButton can't be fully clicked

- fix the control's width (don't have to be explicit, the QQC2 Control
takes care of calculating the implicitWidth/Height automatically based on
contents)
- while at it, fix the metrics to be able to support RTL
languages too (it was off for Arabic)
- some smaller cleanups too
