I removed the vm.continuations requirement on those tests (only SuspendAfterDeath.java and RedefineRunningMethods_Shared.java were actually creating a JVMTI environment though).

>The tests re-running with -XX:-VMContinuations is fine but it does mean they will run twice on the ports without an implementation. The test runtime/jni/IsVirtualThread/IsVirtualThread.java is an example where it only runs once on these ports, at the cost of additional `@test` tag.

I see, I removed the extra run and created another @test tag for that with `@requires vm.continuations`, like it is done in IsVirtualThread.java.
