Disable the FFI specific test suites in Java 19

[ChengJin01]

The change is to only enable the FFI specific test suites
on Java 18 given there is on backward compatibility between
Java 19 and Java 18 in terms of FFI APIs.

The test suites intended for Java 18 become invalid once ibmruntimes/openj9-openjdk-jdk#443 (new APs in Java 19) gets merged to the repo, in which case we will need to move all test suites with all updated APIs to Java19andUp.

Note: this PR must be merged before the code at #15091 to avoid running tests in builds.

Jenkins test sanity plinux jdk18,jdk17

It seems the test cases will be compiled in Java 19 (reminded by Jack when compiling with openj9-staging), which means somewhere in build.xml needs to be updated accordingly to prevent them from being compiling. Will double-check again to see how to deal with this.

[ChengJin01]

I just updated all build.xml in Java16andUp, Java17andUp and Java18andUp to ensure the FFI specific test cases are only compiled with the correct JDK version given there is no backward compatibility with each other. Meanwhile, the test in foreignMemoryAccess is restricted to Java16/17/18 as the scope specific APIs are replaced with the MemorySession specific APIs in Java 19, which are moved to java.base.

@llxia, please take a look at the test setting/framework in Java 16, 17 and 18 (including build.xml and playlist.xml, etc) to see whether it works this way as expected.

LGTM

I've updated the build.xml to adding the missing setting for the TestUtilities directory and verified locally to pass the compilation in Java 17 & 18. I'm not aware that the changes have anything to do with Java 11.

@llxia, please run jenkins again to see whether everything works fine with the update.
