<AWT Dev> [12] Review Request: 8214461 Some unused classes may be removed

[Sergey Bylokhov]

Hello.
Please review the fix for jdk 12.

Bug: https://bugs.openjdk.java.net/browse/JDK-8214461
Webrev: http://cr.openjdk.java.net/~serb/8214461/webrev.00

We have a few internal classes/interfaces which currently unused and may be removed:
  - sun.awt.image.BadDepthException.java: looks like it was never used
  - sun.awt.TracedEventQueue.java: was used for logging
  - sun.awt.Graphics2Delegate.java: currently unused
