Screen Capture: Extend RadioButtonGroup to support both icon and label

RadioIconButtonGroup only supported icon buttons. However, the same UI
applies to buttons that have a label, or both an icon and label. This
converts RadioIconButtonGroup to RadioButtonGroup and changes the
component API to accept a new RadioButtonGroupItem argument.
