RFR: 8304996: Add missing HandleMarks [v2]

[David Holmes]

> The review for [JDK-8304147](https://bugs.openjdk.org/browse/JDK-8304147) pointed out that the top-level HandleMark in dump_for_exit (added to replace the previous coverage from a HandleMarkCleaner in JVM_ENTRY) was not in the right place as no Handles were being used there. Removing that HM and fixing up the ensuing failures led to a set of fixes where HM's were missing at the place of Handle usage.
