[NE16] wire --enable-3x3 flag in generateNetwork.py

The --enable-3x3 flag was parsed by the runner script but never passed
to generateNetwork.py, so NE16Engine.enable3x3 was always False. DW 3x3
and Dense 3x3 convolutions silently fell back to the PULP cluster
instead of dispatching to NE16. Add the flag and set it on the engine.
