RFR: 7903193: [jtreg] build and test failures using JDK 18

[Jaikiran Pai]

Can I please get a review of this test only changes, which proposes to address the current failure in jtreg self tests when Java 18 or higher is used to build and test jtreg?

As noted in the following issues:
https://bugs.openjdk.org/browse/CODETOOLS-7903193
https://bugs.openjdk.org/browse/CODETOOLS-7903646
https://bugs.openjdk.org/browse/CODETOOLS-7903645

these self tests in jtreg which rely on SecurityManager, no longer pass when used with Java 18 or higher, since starting Java 18 the setting of SecurityManager throws an UnsupportedOperationException.

Changes in this PR, include updates to test files which check for the Java version being used to run these tests and then decide whether or not to include some specific tests that only pass when a SecurityManager is set.

I've run these changes locally (on macos M1) and on a linux setup, both with Java 17  and Java 21. The tests all pass on these versions.

I've also run this on a headless system to make sure the `ReportOnlyTest.gmk` does indeed properly check the correct values on a headless system (both Java 17 and 21). I think this change should address the issue that Ludvig @LudwikJaniuk had run into.
