COMPMID-3239: Fix projection and peephole in NEQLSTMLayer

- Peephole and projection has been fixed to be working
- Small internal kernel copying data between tensors to
  cover the case where num_units and output_size is different
  is added.

Below is strictly outside of this patch's scope but are changes
helping this patch working (directly or indirectly) or making
NEQLSTM more complete.

- Consideration for layer normalization is added to InfoHelpers
- QSYMM8 data type is added to helper function to
  print out tensors.
- NE/CLLSTMLayer::validate() logic has been modified to use correct
  value for shape validation.
