Verify more constants are not loaded at startup #18012

Loading different constants can be tricky with all the requires in Homebrew so we want to strengthen the existing checks to make sure that things are not getting required when there is a performance penalty. This expands the existing check to include more constants beyond `Formula` that we don't expect to be defined and that pull in a lot of other dependencies.

Nice work @apainintheneck! Any other big constants you think we could add in here? I'm happy to take a look and suggest some if that's be helpful. My thinking would just be to add various require to global.rb and use brew prof to see which ones have the biggest impact on a brew ruby -e 'puts :foo' (or similar quick command that goes through Ruby-land) output.

There are a few more that we don't want to be loaded at start up but they are required by some of the existing files in this list so it's not strictly necessary to add them here. I'm thinking of FormulaInstaller and Keg in this case. That being said the check here is really simple so there is essentially no cost to us expanding this list. Feel free to take a look and add any that seem mildly suspicious to the list. Homebrew::API is an example of a borderline one that I decided to add on a whim.

Thanks @apainintheneck. Inspired by your great work here: I've opened #18065 as a follow-up.
I feel pretty confident after this that I can stop asking people to not add them to global.rb as CI will now catch this instead. Couldn't have done it without your idea here, wonderful stuff 👏🏻 😍

Formulathat we don't expect to be defined and that pull in a lot of other dependencies.Note: This currently fails the
TapandHomebrew::APIchecks but those should resolve themselves after #18010 gets merged in.Note 2: This PR conflicts with #18008 so we should wait until that one gets merged in.
