Prior to this CL, the NNAPI QoS deadline is a strict deadline: a task with a deadline must either complete or abort by the deadline. To avoid as much overhead as possible, it is requested for Android R to have a relaxed deadline, where the task *may* be aborted after the deadline has passed or when the task is estimated to take too long. Because the deadline is now relaxed, the querying method IDevice::supportsDeadlines can be removed.
