Check jdk_util subtargets to see if TEST_VARIATION_DUMP is needed

[llxia]

We split jdk_util into 4 smaller targets via https://github.com/adoptium/aqa-tests/issues/6704. For jdk_util, TEST_VARIATION_DUMP is added because there are some tests that intentionally cause OOM.

We need to check 4 jdk_util subtargets to see if TEST_VARIATION_DUMP is needed jdk_util_other jdk_collections jdk_concurrent jdk_stream

@Amrutha-Kanhirathingal could you please work on this? Thanks

No Out of memory issues observed in linux,aix & windows machines .but noticed that few tests (eg : jdk_collections_2,jdk_concurrent_2 ,jdk_stream_2 for linux) are skipped due to jvm options ( -Xverbosegclog ).
