jdk19 openjdk java/util/concurrent/tck/JSR166TestCase.java testAwaitUninterruptibly(ReentrantReadWriteLockTest): timed out waiting for thread to enter thread state WAITING

The test passes locally. We can re-enable the test: - JDK19: https://github.com/adoptium/aqa-tests/blob/26b24753e1587b474180af2070bdff4759509b27/openjdk/excludes/ProblemList_openjdk19-openj9.txt#L442 - JDK20: https://github.com/adoptium/aqa-tests/blob/26b24753e1587b474180af2070bdff4759509b27/openjdk/excludes/ProblemList_openjdk20-openj9.txt#L483

re https://github.com/eclipse-openj9/openj9/issues/15181#issuecomment-1278033949: - `ELS` -> `EntryLocalStorage`. Instead of the abbreviation, a more verbose naming is better for readability. - Can default methods be used in the interface to avoid duplication?

@hangshao0 The test needs to be re-enabled, and then the `test excluded` tag should be removed. - JDK19: https://github.com/adoptium/aqa-tests/blob/a74405ca1262c4e50ea0a88e9cb27ade2dd60179/openjdk/excludes/ProblemList_openjdk19-openj9.txt#L443 - JDK20: https://github.com/adoptium/aqa-tests/blob/a74405ca1262c4e50ea0a88e9cb27ade2dd60179/openjdk/excludes/ProblemList_openjdk20-openj9.txt#L483

JDK19 j9vm.226 * ** ASSERTION FAILED ** at openj9/runtime/vm/ContinuationHelpers.cpp:155: ((currentThread->currentContinuation) != NULL)

Closing. `StructuredTaskScopeTest` passes now. No failures seen in https://openj9-jenkins.osuosl.org/job/Grinder/2348/ (100x grinder). It has been re-enabled for JDK20; see https://github.com/adoptium/aqa-tests/blob/master/openjdk/excludes/ProblemList_openjdk20-openj9.txt; the exclude has been removed.

Re-opening since the fix also needs to be back-ported to the 0.37 release branch.

~Now, this failure is also seen in a certification test. So, it will need to be fixed for Java 21.~ I misinterpreted the behaviour highlighted in https://github.com/eclipse-openj9/openj9/pull/17938 with the failure...

For JDK19+, we implemented lazy allocation of TLS array and thread-data in https://github.com/eclipse-openj9/openj9/pull/15541. **Correction:** This does not include the first solution from https://github.com/eclipse-openj9/openj9/issues/15853#issuecomment-1474958089 which mentions of delaying TLS key creation....
