*   NNAPI
    *   Set default value for
        `StatefulNnApiDelegate::Options::max_number_delegated_partitions` to 3.
    *   Add capability to disable `NNAPI` CPU and check `NNAPI` Errno.
    *   Fix crashes when using `NNAPI` with target accelerator specified with
        model containing Conv2d or FullyConnected or LSTM nodes with quantized
        weights.
