Remove unparseable attributes from all nodes (#14780)

In my initial pass through enabling Breathe I tried to leave a minimal footprint of external modification to the generated files. In this particular case it looks like the problematic attributes can appear in more places than I originally observed. I never observed this behavior in that PR, but I don't know if these now appear due to something that merged after #13846 or something else changing in the environment (e.g. a Sphinx or doxygen behavior etc). Nonetheless, blanket wiping these is the simpler and safer option. The docs build successfully locally with this change.
