Backport Virtual Thread Changes from JDK-next

ParkALot launches a number of virtual threads and expects each thread
to park and unpark 500_000 times. The test takes a lot of time to
execute, leading to timeouts in Jenkins testing.

The number of park and unpark iterations is reduced to 5_000, which is
sufficient to verify functional behaviour. Further, the reduced
iterations allow the test to pass in a reasonable time in Jenkins
testing.

vm.debug is set to false for OpenJ9. So, the vm.debug=true variant is
left unmodified.

Remove definitions of unused make macros

Adjust ThreadListStackTracesTest for checkReentrantLock
to be ready when the virtual thread state is WAITING after
the reentrant lock parks the virtual thread. When the
virtual thread is mounted, the virtual thread state, which
is obtained from the carrier thread, can transition
between WAITING and RUNNABLE before the virtual thread is
parked on the lock.
