…, r=jackh726 make `order_dependent_trait_objects` show up in future-breakage reports tried to change it to a hard error in rust-lang#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 rust-lang#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.

Given this only changes unstable marker trait behavior, fine to land with open issue referenced in known bug |

fixes #102360
I have no idea whether this actually removed all places where
'staticmatters. Without canonicalization it's very easy to accidentally rely on'staticagain. Blocked on changing theorder_dependent_trait_objectsfuture-compat lint to a hard errorr? @nikomatsakis
