OpenJDK test flag vm.continuations is false but should be true

If there are tests that fail when vm.continuations is set to true, we should exclude them and create issues to track.

Personal build in progress to verify the tests that require vm.continuations flag

[fengxue-IS]

sanity.openjdk failures:

java/lang/Thread/virtual/CarrierThreadWaits.java
java/lang/Thread/virtual/GetStackTrace.java
jdk/internal/vm/Continuation/MovingCompWindow.java (OpenJDK specific, doesn't apply to OpenJ9)

extended.openjdk failures:

serviceability/jvmti/vthread/FollowReferences/VThreadStackRefTest.java
serviceability/jvmti/vthread/ThreadStateTest/ThreadStateTest.java
serviceability/jvmti/vthread/ToggleNotifyJvmtiTest/ToggleNotifyJvmtiTest.java (OpenJDK specific, doesn't apply to OpenJ9)

I will open Issue/PR on test failure and exclude this before enabling the vm.continuations flag.

Pls exclude the OpenJDK specific tests under a different issue, as we will mark it with the perm excluded label and close it.

Created issues to track test failure:
#18051
#18052
#18053
#18054
Exclude PR adoptium/aqa-tests#4738

Perm exclude for OpenJDK specific testing under #18049 and exclude PR adoptium/aqa-tests#4737

Closing: OpenJDK test flag vm.continuations has been enabled; the failing tests have been excluded; and standalone issues have been opened for each failure.
