+ * Creates a prepared model for execution.
+ *
+ * prepareModel is used to make any necessary transformations or alternative
+ * representations to a model for execution, possiblly including
+ * transformations on the constant data, optimization on the model's graph,
+ * or compilation into the device's native binary format. The model itself
+ * is not changed.
+ *
+ * The model is prepared asynchronously with respect to the caller. The
+ * prepareModel function must verify the inputs to the prepareModel function
+ * are correct. If there is an error, prepareModel must immediately invoke
+ * the callback with the appropriate ErrorStatus value and nullptr for the
+ * IPreparedModel, then return with the same ErrorStatus. If the inputs to
+ * the prepareModel function are valid and there is no error, prepareModel
+ * must launch an asynchronous task to prepare the model in the background,
+ * and immediately return from prepareModel with ErrorStatus::NONE. If the
+ * asynchronous task fails to launch, prepareModel must immediately invoke
+ * the callback with ErrorStatus::GENERAL_FAILURE and nullptr for the
+ * IPreparedModel, then return with ErrorStatus::GENERAL_FAILURE.
+ *
+ * When the asynchronous task has finished preparing the model, it must
+ * immediately invoke the callback function provided as an input to
+ * prepareModel. If the model was prepared successfully, the callback object
+ * must be invoked with an error status of ErrorStatus::NONE and the
+ * produced IPreparedModel object. If an error occurred preparing the model,
+ * the callback object must be invoked with the appropriate ErrorStatus
+ * value and nullptr for the IPreparedModel.
+ *
+ * The only information that may be unknown to the model at this stage is
+ * the shape of the tensors, which may only be known at execution time. As
+ * such, some driver services may return partially prepared models, where
+ * the prepared model can only be finished when it is paired with a set of
+ * inputs to the model. Note that the same prepared model object can be
+ * used with different shapes of inputs on different (possibly concurrent)
+ * executions.
+ *
+ * Multiple threads can call prepareModel on the same model concurrently.
+ *
+ * @param model The model to be prepared for execution.
+ * @param callback A callback object used to return the error status of
+ * preparing the model for execution and the prepared model
+ * if successful, nullptr otherwise. The callback object's
+ * notify function must be called exactly once, even if the
+ * model could not be prepared.
+ * @return status Error status of launching a task which prepares the model
+ * in the background; must be:
+ * - NONE if preparation task is successfully launched
+ * - DEVICE_UNAVAILABLE if driver is offline or busy
+ * - GENERAL_FAILURE if there is an unspecified error
+ * - INVALID_ARGUMENT if one of the input arguments is
+ * invalid
