Split anv_xe_wait_exec_queue_idle() into 2 functions, the first function creates the syncobj and prepares it to be signaled when the last workload in queue is completed. And the second one that calls the first function, then waits for the syncobj to be signaled and destroy the syncobj. The main reason for that is that the first function can be reused in Iris and a future patch will add another user, so lets share it. No changes in behavior are expected here.
