IVGCVSW-4549 Add front end for new QLSTM layer

* Added new layer QLstm (Android R HAL 1.3)
* Made necessary updates to APIs
* Added unit tests
* This layer is functionally equivalent to the
  original unquantized LSTM layer with some
  additonal quantization features added. Due
  to this, original LstmParams are used for
  this layer.
