RFR: 8355221: Get rid of unnecessary override of JDIBase.breakpointForCommunication in nsk/jdi tests

[Chris Plummer]

The following tests all override the JDIBase.breakpointForCommunication() method, but no longer need too:

vmTestbase/nsk/jdi/ClassPrepareRequest/addClassExclusionFilter/filter003.java
vmTestbase/nsk/jdi/ClassPrepareRequest/addClassFilter_rt/filter_rt002.java
vmTestbase/nsk/jdi/ClassPrepareRequest/addClassFilter_s/filter_s002.java
vmTestbase/nsk/jdi/EventRequestManager/classPrepareRequests/clsprepreq002.java
vmTestbase/nsk/jdi/EventRequestManager/methodExitRequests/methexitreq002.java
vmTestbase/nsk/jdi/MethodEntryRequest/addClassExclusionFilter/filter002.java
vmTestbase/nsk/jdi/MethodExitRequest/addClassExclusionFilter/filter002.java

The override was to fix [JDK-8203809](https://bugs.openjdk.org/browse/JDK-8203809). It filters out unexpected events due to system threads (namely Graal java compiler threads). However, there is now a JDIBase.breakpointForCommunication() version that does the same, so the override can be removed. The new version takes the debuggeeName argument that the override versions currently use to filter events based on it.
