    Fix sizing of CheckBox and RadioButton · b738ebbb

    KQuickStyleItem manages its implicit size internally. Overriding it on the QML side makes it non-deterministic
    which assignment wins and might cause unexpected re-evaluation of the size causing it to change.
    Moreover, the CheckIndicator implicit size is based on sizeFromContents for CT_CheckBox, which in case of Breeze
    (but not the Qt built-in styles) already contains some extra padding on the side between checkbox and label.
    Instead of using that for layouting our full checkbox (indicator + label), do what qqc1 did and use
    PM_CheckBoxLabelSpacing for spacing and PM_IndicatorWidth as size hint for the indicator.
    Also while at it for radio buttons use the appropriate (PM_RadioButtonLabelSpacing and PM_ExclusiveIndicatorWidth) hints.
    This makes QQC2 CheckBox and RadioButton layouted pixel-perfect to their QWidget counterparts and also fixes
    it randomly changing size hints as you switch between pages as demonstrated by the bug report.
