#738: Add route data to ComputedBoundsAction

Thanks Martin. Code seems to work fine.
I have tested it by changing the routerKind of the workflow example edge creation handlers to "manhattan".

I have a few inline suggestions and one more general question:

I personally find it a bit odd that an action called "ComputedBoundsAction" also contains the routing points. Also by directly adapting the "ComputedBoundsAction" which we might introduce an inconsistency/incompatibility with the original ComputedBoundsAction from sprotty.

Maybe it would be better to use a dedicated ComputedRoutingPointsOperation and wrap it together with the ComputedBoundsOperation in a "CompoundOperation`?

@tortmayr Thank you very much for your feedback, I adapted the code accordingly. Regarding a dedicated operation for the routing points, I opted against it since the client-side layout information is currently all part of the ComputedBoundsAction, also the alignment. Furthermore, this action carries a specific meaning as the ComputedBoundsActionHandler will directly submit the model afterwards, so splitting that into two operations would make their handling more difficult.

Thanks. Code looks good to me an works like a charm.
