Cleanup: Nodes, silence Clang-Tidy readability-function-size

Add a `NOLINT` marker to explicitly silence a warning from Clang-Tidy's
`readability-function-size` rule for the `node_type_base()` function.
This function is indeed huge, but that is because a lot of macros are
expanded. Before expansion things are still not small, but still
understandable & expandable.

No functional changes.
