MLBEDSW-10533: Don't fuse transpose to an op with OFM slice

* Don't fuse transpose to an op with OFM slice
* Also, when fusing a transpose, the primary op should inherit the
  fused op's OFM slice. Otherwise we might end up with different
  shapes on OFM slice and OFM and in that case OFM slice shape will
  be used later on.
