Check jdk_util subtargets to see if TEST_VARIATION_DUMP is needed

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

Locate the definitions for the four named subtargets: jdk_util_other, jdk_collections, jdk_concurrent, and jdk_stream. Compare their tests with the OOM-related reason for TEST_VARIATION_DUMP in jdk_util, then determine whether each subtarget needs that setting; done means all four have the appropriate configuration.
