RFR: 8244537: JDI tests fail due to "ERROR: Exception : nsk.share.jdi.JDITestRuntimeException: JDITestRuntimeException : ** event IS NOT a breakpoint **"

[Leonid Mesnik]

Hi

Could you please review following fix which suspends debugger VM while enabling/disabling events. 

All changed tests fail intermittently getting unexpected events instead of breakpoint used for communication between debugger/debuggee VM. The tests request different events and verify request's properties but don't process/verify events themselves. Test doesn't aware if events are generated or not. The vm suspension doesn't affect JDWP native agent and it still should get and verify JDWP commands.
