* - NONE if the asynchronous task successfully prepared the
* model
* - DEVICE_UNAVAILABLE if driver is offline or busy
* - GENERAL_FAILURE if the asynchronous task resulted in an
* unspecified error
* - INVALID_ARGUMENT if one of the input arguments to

* - MISSED_DEADLINE_* if the preparation is aborted because
* the model cannot be prepared by the deadline
* - RESOURCE_EXHAUSTED_* if the task was aborted by the
* driver
* @param preparedModel A model that has been asynchronously prepared for
* execution. If the model was unable to be prepared
* due to an error, nullptr must be passed in place of
