[jdk22u] RFR: 8330027: Identity hashes of archived objects must be based on a reproducible random seed

[Thomas Stuefe]

This fixes an issue with CDS archive reproducibility that can happen under rare circumstances. See original JBS issue for details.

I had to manually resolve the hunk in src/hotspot/share/cds/heapShared.cpp because both
- 8251330: Reorder CDS archived heap to speed up relocation
- 8329431: Improve speed of writing CDS heap objects
were missing. 

Resolve was trivial.
