* add WakeupTraversal_WithExitedThreads

* In the TestEVM_WakeupTraversal_WithExitedThreads test, explicitly set the current active thread to exited state (activeThread.Exited = true) to test the wakeup traversal behavior when the active thread has exited && Modified test cases by resetting the active thread's index from exitedThreadIdx to avoid duplicate settings and confusion.

* setting Futex fields with varying values.
