RFR: 8195600: [Graal] jdi tests timeouts with Graal because debuggee vm is not resumed

[Daniil Titov]

Please review the change that fixes the failing tests when running with Graal. The issue originally 
included several vmTestbase/nsk/jdi tests but only 2 of them still fail:
- vmTestbase/nsk/jdi/VirtualMachine/instanceCounts/instancecounts003/instancecounts003.java
- vmTestbase/nsk/jdi/ObjectReference/referringObjects/referringObjects002/referringObjects002.java

The problem with these two tests is that they consume all memory to force the class unloading that 
results in the exception during JVMCI compiler initialization and the test failure.
 
The fix filters these tests out to not run with Graal compiler.
