Op request: layer normalization

[gaikwadrahul8]

Layer normalization is available in tensorflow https://www.tensorflow.org/api_docs/python/tf/keras/layers/LayerNormalization
It is not part of the tflite supported ops
https://github.com/tensorflow/tensorflow/blob/master/tensorflow/lite/builtin_ops.h

I would like to request support for this op. Please let me know if it is in development or scoped for future release.
