RFR: JDK-8357082 : Stabilize and add debug logs to CopyAreaOOB.java [v2]

[Harshitha Onkar]

> 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.
