JDK-8357082 : Stabilize and add debug logs to CopyAreaOOB.java

[honkar-jdk]

CopyAreaOOB.java was failing intermittently on some platforms on CI but recently it started to fail more frequently on macos-aarch64 when the entire test suite runs.

Test failure is not reproducible when the test is run individually (multiple times) on CI.

Rewritten the test and added debug logs that will be helpful to figure out the issue.

• Added code to capture screenshot (entire screen as well as the frame) in case of failure.
• Since it tests multiple regions added a StringBuffer to consolidate the error logs before throwing RuntimeException.

You do not need to call all these methods on the EDT, these are AWT components that should handle multithreaded usage (main/EDT/toolkit threads). It is possible that the issue is only reproducible on macOS due to synchronization problems related to the metal pipeline?
