RFR: 8075916: The regression-swing case failed as colored text is not shown on disabled checkbox and radio button with Nimbus LAF [v2]

[Prasanta Sadhukhan]

> CheckBox.disabledText and RadioButton.disabledText color UIProperty is not honoured by Nimbus L&F when disabled text is drawn for JCheckBox and JRadioButton, so disabled text color was rendered incorrectly.
> Fix is to honour these UIProperty color if they are set by user, else use the color from the component or via getColorForState().
> 
> Closed test as mentioned in JBS is used to check the fix.
