RFR 8203809: [Graal] JDI tests fail with: JDITestRuntimeException : ** event IS NOT a breakpoint **

[Daniil Titov]

Please review the changes that fix failure of 6 JDI tests run with Graal.

The problem here is that currently the tests filter out only 2 specific JFR events (nsk.share.jdi.EventsFilter.filtered()) before analyzing them and fail if the received event doesn't match the expected one.  But with Graal turned on new events generated by the compiler thread are occasionally found in the event queue and cause the tests failure. The fix makes the tests to use an additional check to filter out events not related to the debuggee class.
