[jdk17u-dev] RFR: 8270894: Use acquire semantics in ObjectSynchronizer::read_stable_mark()

[Aleksey Shipilev]

Unclean backport to improve synchronization code reliability. Does not apply cleanly due to later BiasedLocking retirement, which failed a hunk in `ObjectSynchronizer::inflate_helper`, applied that hunk by hand. Additionally, I rewrote the new definition to match what upstream has. This completes the [JDK-8272654](https://bugs.openjdk.org/browse/JDK-8272654) backport.

Additional testing:
 - [ ] Linux x86_64 fastdebug `tier1`
 - [ ] Linux x86_64 fastdebug `tier2`
 - [ ] Linux x86_64 fastdebug `tier3`
