RFR JDK-8233638 [TESTBUG] Swing test ScreenMenuBarInputTwice.java fails on macos

[Prasanta Sadhukhan]

Hi All,

Please review a test bug fix for an issue where it is seen the test was failing 
on macOS during nightly testing.
It was found the test failed with the reason "IllegalComponentStateException: 
component must be showing on the screen to determine its location”
which was because the test calls 
Util.getCenterPoint(menu);
without giving it enough time for menu to be shown on screen. 
Test is updated to add waitForIdle() and delay() between the UI component is 
setup 
and test is executed for that component.

It now passed on macOS on mach5 for several iterations (mach5 job details in 
JBS)
