Mac: SQE needs API to determine current menu state on Mac

It should be possible to find current menu state from java code. The way it is done for Swing, JMenuBar and JMenuItem and JMenu components, although invisible, reflect selected/expanded properties which are actually set in Mac OS X native menu. It does not matter whether this would be done the same way in FX or somehow differently as long as a test code is able to determine menu/submenu selection.

This is required for automation of single app menu bar testing. Rest could be done similar to how it is done in Jemmy v2 for Swing.
