Previously, node types had a callback that creates internal links. Pretty much all nodes used the same callback though. The exceptions are the reroute node (which probably shouldn't be mutable anyway) and some input/output nodes that are not mutable. Removing the callback helps with D13246, because it makes it easier to reason about which internal links are created and when they change. In the future, the internal links should be part of the node declaration.
