RFR: 8269523: runtime/Safepoint/TestAbortOnVMOperationTimeout.java failed when expecting 'VM operation took too long' [v3]

[David Holmes]

> Please review this simple test adjustment:
>  - dropped 5ms timeout as we have seen execution as low as 2ms
>  - enabled GC logging
>  - report output in all cases to allow ease of analysis
> 
> Testing: ran 10x on macos/linux/Windows x64 and macos Aarch64 to check execution times and adjusted test accordingly
> 
> Thanks,
