Do direct notification of backend nodeswip/refactor

Since aspect manager is now on main thread, we can directly update
backend nodes safely. Track nodes which have changed properties and
notify the backend nodes as part of the frame loop.
This avoid allocating and delivering many change messages.

To follow:
- implement on all nodes
- look at backend to frontend syncing
- figure out what to do with non property messages (components
  added/removed, commands, ...)
