Directories in intern/ were selectively formatted based on
paths in `tools/utils_maintenance/clang_format_paths.py`.
This had the following problems:
- Editing files inside intern/ would auto-format on save with editors
setup to auto-format as there was nothing to disable formatting.
- Some directories were missing (by accident it seems).
Resolve by formatting all of `./intern/` exclude except for
`./intern/itasc/` which includes ITASC & KDL versions we might
want to sync with upstream.
