Currently if any one of the nodes change in the nodes prop, we are rebuild all of the nodes in the diagramming library. We should only re-build the changed nodes to avoid additional re-renders.

This ticket involves updating the logic in `convertToInternalNodes` to take in the existing nodes, do a deep equality check on the new nodes coming in (on the library consumer side we need to make sure the node and fields data doesn't change object/field references without real data changes), and only re-build the objects of the nodes that have changed. That way react-flow can avoid re-rendering existing nodes as it does an equality check on the nodes passed to it:
