Takes #3087 further by adding an event that will dispatch on any page to confirm that all graphers have loaded.
This is necessary for this site-screenshots PR so that we can reliably take a screenshot once the page is ready instead of sleeping an arbitrary amount of time that will either be too long or too short for most pages.
I can imagine we'll forget this code exists and accidentally break it from time to time, but once we have a proper site screenshots test on every page type, we'll be able to make our CI tests fail until it's resolved (or confidently vetoed, like we do with the SVG tester)
