Our v11 release will require node 18+. Since fetch has been introduced in these node versions, we can remove our dependency on third party fetch implementations.

This change removes our usage of fetch variants undici and node-fetch for our node target builds and our CI tools.

With the removal of fetch we no long need to create a node bundle for functions. Instead the sourcebase may become isomorphic, so long as we remove the older node sources. And that's what the PR does!
