* provided with the ErrorStatus from the execution. If the asynchronous task is
* not launched, either notify_1_2 or notify must be invoked with the appropriate

* @param status Error status returned from launching the asynchronous task
* (if the launch fails) or from the asynchronous task itself
* (if the launch succeeds). Must be:
* - NONE if the asynchronous execution was successful
* - DEVICE_UNAVAILABLE if driver is offline or busy
* - GENERAL_FAILURE if the asynchronous task resulted in an
* unspecified error
* - OUTPUT_INSUFFICIENT_SIZE if at least one output
* operand buffer is not large enough to store the
* corresponding output
* - INVALID_ARGUMENT if one of the input arguments to
* prepareModel is invalid
* @param outputShapes A list of shape information of model output operands.
* The index into "outputShapes" corresponds with to index
* of the output operand in the Request outputs vector.
* outputShapes must be empty unless the status is either
* @return Timing Duration of execution. Unless MeasureTiming::YES was passed when
* launching the execution and status is NONE, all times must
* be reported as UINT64_MAX. A driver may choose to report
* any time as UINT64_MAX, indicating that particular measurement is
