Refactor: Nodes: avoid using NOD_static_types.hh when creating node types

This removes the second to last usage of `NOD_static_types.hh` which we intend
to remove. A nice benefit is that the idname is now finally more explicit when a
node is registered. Previously it was difficult to search for the definition of
a node in the code when one had only the idname, which is the main identifier
for nodes.

The main change is in `node_type_base`.
