<Swing Dev> RFR: 8194126: Regression automated Test '/open/test/jdk/javax/swing/JColorChooser/Test7194184.java' fails

[Prasanta Sadhukhan]

Please review a test fix for an issue where the color is not chosen correctly.
The issue seems to stem from the fact that keys are not processed properly so the proper color is not chosen.
Fixed by adding autoDelay during processing of key events and also made EDT change to invokeAndWait from invokeLater.
Also, move the frame to center of screen and do cleanup at finally block.
Mach5 job was run for several iteration on all 3 platforms. Link in JBS
