Various fixes and improvements for recent Java and Jenkins versions

• aragozin/jvm-tools@0f9fcb9 is needed for Java 10+ string support. It first landed in version 0.11 of hprof-heap, but the maintainer later split the library out into a separate repository, see https://github.com/aragozin/heaplib, so this PR swaps to the new artifact. I have been running this for years but forgot to file a PR for it.
• FlowExecutionList.Storage jenkinsci/workflow-api-plugin#370 broke this script. I added support for DefaultStorage in this PR
• I added Hex-encoded output for easier use with tools like Eclipse MAT and started printing the address of the objects used to find the WorkflowRun to make things easier to link in cases where CpsFlowExecution.cleanUpHeap has already run

Known issues:

• I have run into FastHprofHeap throws on unknown instanceID in idToInstanceNumber aragozin/heaplib#8 in the past (perhaps with dumps from newer JDKs, but I don't recall exactly). aragozin/heaplib@master...dwnusbaum:heaplib:fasthprofheap-idtoinstancenumber-uoe seems to work fine to avoid the issue if you run into it.
• Today I saw the following error with a Java 21 heap dump. Not sure about fixing it, going forward I will probably switch to just writing OQL scripts for MAT instead.

Exception in thread "main" org.netbeans.lib.profiler.heap.HeapOffsetMap$PageNotFoundEndOfHeapReachedExcpetion: No such ID, end of heap reached

I have tested this fix, and it resolves the issues I was encountering with the actual Pipeline job names not being printed correctly when analyzing a heap dump from openjdk 11.0.24:
OpenJDK 64-Bit Server VM (Red_Hat-11.0.24.0.8-2) (build 11.0.24+8-LTS, mixed mode, sharing)
