JVMTI functions RawMonitorEnter and RawMonitorExit can be invoked from Java code using native methods. ownedMonitorCount is incremented for the current J9VMThread in RawMonitorEnter after successfully acquiring the monitor, and it is decremented for the current J9VMThread in RawMonitorExit after successfully releasing the monitor. This prevents virtual threads to yield if it owns a monitor. Related: eclipse-openj9#16753 Signed-off-by: Babneet Singh <sbabneet@ca.ibm.com>

JVMTI functions RawMonitorEnter and RawMonitorExit can be invoked
from Java code using native methods.
ownedMonitorCount is incremented for the current J9VMThread in
RawMonitorEnter after successfully acquiring the monitor, and
it is decremented for the current J9VMThread in RawMonitorExit
after successfully releasing the monitor.
This prevents virtual threads to yield if it owns a monitor.
