*   `tf.while_loop` emits a StatelessWhile op if the cond and body functions are
    stateless and do not touch any resources.
*   Refactors code in Quant8 LSTM support to reduce TFLite binary size.
*   Add support of local soft device placement for eager op.
*   Add HW acceleration support for `LogSoftMax`.
*   Added a function `nested_value_rowids` for ragged tensors.
*   Add guard to avoid acceleration of L2 Normalization with input rank != 4
