This changes the Switch node so that it is implemented directly as a lazy-function, instead of as a normal geometry node which uses `GeoNodeExecParams`. This improves the design of the layered execution api, where different nodes can be implemented at a proper different abstraction level. The simplest kinds of nodes are implemented as multi-function, then there is `GeoNodeExecParams` and more specialized nodes are implemented as lazy-function. The switch node is special in the sense that it currently needs extra behavior in the lazy-function graph generation anyway. `GeoNodeExecParams` can be simplified as well, because the Switch node was the only one that used the `lazy_` methods. We could consider adding back lazy-input functionality to normal geometry nodes as it becomes necessary. Ideally, that could be integrated with the node declaration.
