Crash in Compiled_method=<...> or VM Access Assertion (vmThread)->publicFlags & J9_PUBLIC_FLAGS_VM_ACCESS

[babsingh]

The root cause of the below failures is jitMonitorExit() passing in the incorrect currentThread.

The initial diagnosis of the below failures was done in https://github.com/eclipse-openj9/openj9/issues/21717.

Note: The old issues have been closed as a duplicate of this issue. The tests excluded for those issues will need to be re-enabled once this issue is closed. I haven't removed the test excluded label from the old issues since the exclude files haven't been updated. The test excluded label from the old issues should also be removed once the tests are re-enabled before closing this issue.
