Rollup merge of #102635 - lcnr:incoherent_auto_trait_objects, r=jackh726

make `order_dependent_trait_objects` show up in future-breakage reports

tried to change it to a hard error in #102474 but breaking the more than 1000 dependents of `traitobject` doesn't feel great 😅

This lint has existed since more than 3 years now and the way this is currently implemented is buggy and will break with #102472. imo we should upgrade it to also report for dependencies and maybe also backport this to beta. Then after maybe 2-3 stable versions I would like to finally convert this lint to a hard error.
