COMPMID-3510 [Interface change] Fix definition of "axis" in NESoftmaxLayer and CLSoftmaxLayer

* [Interface change] "axis" argument is renamed to "reduce_end_axis"

* Unify the meaning of "axis"(now "reduce_end_axis") to be the last axis
  of the first n dimensions (inclusive)to reduce.
  This way the meaning of reduce_end_axis stays the same for both
  positive and negative values: it selects a dimension before which all
  dimensions (including the selected dimension) are reduced.
