I want to give this field a name that's bit less generic and distinguishes it from lazyData (because that one has a different type and is a special case we want to eventually remove).

I'm also about to add an optional prefetchRsc field that represents a prefetched version of the same value. The common suffix is meant to communicate how they are related.

Doing this rename in its own PR because it's a pure find-and-replace, whereas the later steps are not.

Closes NEXT-1846

Do we consider to call it sth like rscNode or any related to "node" as the type is ReactNode, rsc makes me think of rsc payload data

Yeah maybe but even rscNode could refer to something that was rendered by RSC but is not renderable on the client. It would have to be something more like rscReactNode but I don't know if that really does much to clarify. I think in this case we can rely on the type to communicate it.
