[lworld] RFR: 8272041: [lworld] CDS heap dump fails with primitive objects

Two simple fixes to handle primitive objects when dumping the CDS heap:

- When dumping the objects, we enter them into a hashtable. Do not use `oopDesc::identity_hash()` as the hashcode for this table.
- When resetting the header of archived objects, do not call `oopDesc::identity_hash()` on primitive objects.
