Parallelize heap walk for ObjectCount(AfterGC) JFR event collection

        (Provisionally assigning this to myself, but Oli Gillespie [not an Author yet] would do the actual work)

        ObjectCount(AfterGC) JFR event performs the single-threaded heap walk to count instances at GC pauses. After JDK-8215624, we can use the parallel heap walking facilities for this. Should be enough to just call `HeapInspection::populate_table` with the number of available GC workers.
