[lilliput-jdk17u:lilliput] RFR: 8324881: ObjectSynchronizer::inflate(Thread* current...) is invoked for non-current thread

[Roman Kennke]

Backport of https://github.com/openjdk/jdk/commit/a3a2b1fbbf00577ce1d0e3a44e9537e997b30b05

This is a bugfix related to lightweight locking. It's not clean due to various small diffs, e.g. thread-cast, nullptr vs NULL, -XX:+UnlockExperimentalVMOptions and context.
