Small __getstate__ cleanups.

anntzer · anntzer · commit 1f30016999d9 · 2021-12-13T09:21:45.000+01:00
Remove outdated comment in `AxesBase.__getstate__` (we don't cache the
renderer on it anymore).

Remove unnecessary `SubplotSpec.__getstate__` (it has become unnecessary
now that SubplotSpec doesn't hold onto layoutbox/poslayoutbox anymore.)
