RFR: 8281267: VM HeapDumper dumps array classes several times [v5]

[Alex Menkov]

> ClassLoaderDataGraph::classes_do description says:
> // Walking classes through the ClassLoaderDataGraph include array classes.
> So do_load_class callback should not dump arrays for the classes and dumper doesn't need to call Universe::basic_type_classes_do (array classes for primitive types are also reported by ClassLoaderDataGraph::classes_do)

Alex Menkov has updated the pull request incrementally with one additional commit since the last revision:

  removed unused Universe::basic_type_classes_do
