The test serviceability/jvmti/vthread/TestPinCaseWithCFLH need to be removed.

Jaikiran Pai:
The test/hotspot/jtreg/serviceability/jvmti/vthread/TestPinCaseWithCFLH/TestPinCaseWithCFLH.java was a test that was contributed by an external contributor to exercise the -Djdk.tracePinnedThreads=full system property when a javaagent was involved. The jdk.tracePinnedThreads system property is no longer supported by Virtual Threads implemetnation in mainline. that system property was dropped as part of https://github.com/openjdk/jdk/pull/21565 in JDK 24.

Alan Bateman:
I think it was the only way that the JVMTI issue could be duplicated at the time. I did point out several times about jdk.tracePinnedThreads going away.
