RFR: 8198626: java/awt/KeyboardFocusmanager/TypeAhead/TestDialogTypeAhead.html fails on mac

[Pankaj Bansal]

Test java/awt/KeyboardFocusmanager/TypeAhead/TestDialogTypeAhead.html fails on mac fails on Mac. The test fails on my local machine (macOS BigSur) always and on mach5 also. The test uses Robot for mouse clicks and there is no delay or autoDelay set on Robot.

The fix adds set autoDelay on the robot. Along with this, a lot of cleanup is done including removing the local Semaphore class etc. The test passes after the changes on my local mac and mach5 (Link in the JBS)
