RFR: 8204165: Filter out tests requiring class unloading when ClassUnloading is disabled

[coleen.phillimore at oracle.com]

If  you look for ClassUnloadCommon, there are a couple others.  It would 
be good to have these tagged as well, even though the last one tests two 
things.

runtime/appcds/customLoader/UnloadUnregisteredLoaderTest.java
runtime/appcds/customLoader/test-classes/UnloadUnregisteredLoader.java
runtime/logging/LoaderConstraintsTest.java
runtime/BadObjectClass/TestUnloadClassError.java

If you look for triggerUnloading there are more: e.g. 
vmTestbase/metaspace/stressHierarchy.  I assume they pass without class 
unloading though.

Thanks,
Coleen
