perf: provide PubSub to SlickGrid/DataView avoid looping all events

[ghiscoding]

• SlickGrid/SlickDataView allow passing a PubSub in latest major release v5.0 but this change was never applied in Slickgrid-React (though it was applied in all other ports) because I couldn't get it working at first and I had decided to put this aside, but after revisiting this now, I am able to implement the change which will help with perf as describe below
• the perf change is that we no longer need to loop through all SlickGrid/DataView and subscribe to all of the events to then dispatch whenever it triggers, that was the previous approach and wasn't ideal. The new approach is to simply pass the PubSub to both SlickGrid/DataView and let them dispatch whenever necessary without requiring any loop whatsoever
