IVGCVSW-6269 Add support of Unidirectional Sequence Lstm fp32/fp16 to Android

  * Unidirectional Sequence Lstm is supported in android-nn-driver.
  * CTS and VTS pass for Unidirectional Sequence Lstm if there are
    any without weights as inputs. If that isn't the case use the
    tests implemented in the android driver for LSTM.

 Where operations are not supported by the ArmNN Android NN Driver, the driver indicates this to the framework
 appropriately and the framework implements those operations using a CPU implementation.
