gh-37223: Remove invariants commands in global namespace This PR removes the depreciated invariants from #28064 (2019). It's been long enough and we should declutter the tab-autocomplete from these very specific functions. As an aside, I'm not sure why we have: ```py from . import monsky_washnitzer ``` Instead of importing objects from this module, but I have not worked with this myself so am loathed to modify this without further input from the community.
