RFR: 8354234: Remove friends for ObjectMonitor

Thu Apr 10 16:24:52 UTC 2025

Please review this somewhat trivial change to remove unneeded friends from the ObjectMonitor class.  Two functions were made public for use with ObjectSynchronizer and avoid referencing fields directly from other places.
Tested with tier1 sanity.
