Add ability to add a patch without updating data limits #19685
Description
Problem
In sunpy we have come across a case where we want to imshow and image, and then overplot a circle on top of that image. The circle is bigger than the image, and we want to keep the axes limits to those of the image, so ideally we would like a way to add a patch, without the patch updating the data limits. As far as I can tell this isn't possible currently.
To work around this we are using add_artist() instead of add_patch(), but as I understand from #19290 this might change in the future.
Proposed Solution
ax.plot() can take scalex, scaley keywords, that indicate whether the x/y limits are updated, so maybe a similar API for add_patch(), or individual Patch objects would be helpful.

I think @anntzer had a suggested an artist property
autolimthat can be toggled if an artist is going to be in the limit algorithm or not? Parallel toset_layouthttps://matplotlib.org/stable/api/_as_gen/matplotlib.artist.Artist.set_in_layout.htmlanntzer commentedon Mar 11, 2021
#15595 is what I was championing, but it kind of stalled.
FWIW the first snippet at #19296 is what I'm using personally right now (wrapped in a contextmanager).

#15595 seemed to be broadly supported, so it should be able to move forward if someone is excited about it...

Do we agree on the proposed API? #15595 (comment)
Nobody has answered back on that.
