[jdk17u-dev] RFR: 8313081: MonitoringSupport_lock should be unconditionally initialized after 8304074 [v2]

[Paul Hohensee]

> Follow-on bug fix for [JDK-8304074](https://bugs.openjdk.org/browse/JDK-8304074) backport. The lock definition macro changed between 17 and 21, so the definition of MonitoringSupport_lock is different.
