Michael Butler ed8e77bf12 Add Quality of Service to NNAPI HAL
This CL makes the following changes:
* introduces a new Priority enum
* extends ErrorStatus with new error codes
* adds "supportsDeadline" method to IDevice
* adds priority and deadline arguments to IDevice::prepareModel*
* adds deadline argument to IPreparedModel::execute*
* updates IExecutionCallback with new ErrorStatus
* updates current.txt accordingly

* There are three notify methods declared for the IPreparedModelCallback
* interface: notify_1_3, notify_1_2, and notify. One of the three

* task holding this callback has finished preparing the model. If the model was
* successfully prepared, one of the notify methods must be invoked with
* ErrorStatus::NONE and the prepared model. If the model was not able to be
* successfully prepared, one of the notify methods must be invoked with the
* appropriate ErrorStatus and nullptr as the IPreparedModel. If the asynchronous
* task holding this callback fails to launch or if the model provided to
* IDevice::prepareModel is invalid, one of the notify methods must be invoked
* with the appropriate error as well as nullptr for the IPreparedModel.
*
* @param status Error status returned from the asynchronous model
* preparation task; must be:
* - 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
* prepareModel is invalid
* - MISSED_DEADLINE_* if the deadline for executing a model
* cannot be met
* - 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
* the IPreparedModel object.
