RFR: 8300721: Cleanup ProblemList-svc-vthread.txt

[Chris Plummer]

There are a number of entries in ProblemList-svc-vthread.txt that don't have any CRs associated with them. CRs have since been created and the problemlist needs to be updated to reflect this. Here are links to the relevant CRs:

[JDK-8285414](https://bugs.openjdk.org/browse/JDK-8285414): [LOOM] Some nsk/jdi tests fail due to not expecting OPAQUE_FRAME from JVMTI PopFrame()
[JDK-8300712](https://bugs.openjdk.org/browse/JDK-8300712): nsk/jvmti/scenarios/allocation/AP11/ap11t001 fails with the virtual thread wrapper
[JDK-8300711](https://bugs.openjdk.org/browse/JDK-8300711): nsk/jvmti/CompiledMethodUnload/compmethunload001 fails with the virtual thread wrapper
[JDK-8300709](https://bugs.openjdk.org/browse/JDK-8300709): nsk/jvmti/GetObjectMonitorUsage/objmonusage006 test asserts with virtual thread wrapper
[JDK-8300708](https://bugs.openjdk.org/browse/JDK-8300708): some nsk jvmti tests fail with virtual thread wrapper due to missing jvmti missing some virtual thread support
[JDK-8300707](https://bugs.openjdk.org/browse/JDK-8300707): jdb "list" and "repeat" tests fails with virtual thread wrapper

Note the following two tests are covered by the pre-existing [JDK-8285414](https://bugs.openjdk.org/browse/JDK-8285414),  and were move down to the section with other tests problemlisted under this CR:


vmTestbase/nsk/jdb/pop_exception/pop_exception001/pop_exception001.java
vmTestbase/nsk/jdi/VirtualMachine/redefineClasses/redefineclasses002/TestDescription.java


Also, the following test has been removed, so it is being removed from the problemlist:


vmTestbase/nsk/jvmti/Breakpoint/breakpoint001/TestDescription.java
