> The `get_jvmti_thread_state()` function is called from `JvmtiExport::at_single_stepping_point()`.  It can block for virtual threads. Then the `SingleStep` events can be enabled at that point. The incorrect behavior is that the `SingleStep` events will be posted even though the virtual thread has been suspended with the JVMTI `SuspendThread`, `SuspendThreadList`, or `SuspendAllVirtualThreads`. The fix is to add a suspend point for virtual threads to the `get_jvmti_thread_state()` function.
