[lworld] RFR: 8374959: [lworld] runtime/cds/appcds/cacheObject/ArchivedIntegerCacheTest.java fails with --enable-preview

[Matias Saavedra Silva]

One of the test cases in `CheckIntegerCacheApp.java` will fail in preview mode due to the removal of the Integer cache and the behavior of value classes. This test case is now only run in preview mode with an alternate case to verify the preview mode behavior.
