Cleanup: Nodes: Store node group idname in tree type

There was already a utility to retrieve the correct node group idname
from the context, `node_group_idname`, but often it's clearer to
use lower-level arguments, or the context isn't accessible.
Storing the group idname in the tree type makes it accessible
without rewriting it elsewhere.
