[9] Review request for 8165234 Provide a way to not close toggle menu items on mouse click on component level

[Alexandr Scherbatiy]

Hello,
Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8165234
  webrev: http://cr.openjdk.java.net/~alexsch/8165234/webrev.00

  The fix JDK-8158566 adds "CheckBoxMenuItem.closeOnMouseClick" and 
"RadioButtonMenuItem.closeOnMouseClick" properties
  that control toogle menu items closing on mouse click on L&F level.

  The current fix allows to control menu items closing on a component 
level. A toogle menu item
  is not closed on mouse click if the corresponding property is set to 
false either on the L&F or component level.

 Thanks,
 Alexandr.
