RFR: 8277369: Strange behavior of JMenuBar with RIGHT_TO_LEFT orientation, arrow keys behaves opposite traversing through keyboard [v2]

[Prasanta Sadhukhan]

> After applying setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT) to the JMenuBar the arrow keys started to behave the opposite of what expected. Right arrow goes left and Left arrow goes right when trying to traverse through keyboard.
> 
> Fixed to reverse the direction traversal for RTL orientation.
