Rollup merge of #102472 - lcnr:static-in-eval, r=jackh726

stop special-casing `'static` in evaluation

fixes #102360

I have no idea whether this actually removed all places where `'static` matters. Without canonicalization it's very easy to accidentally rely on `'static` again. Blocked on changing the `order_dependent_trait_objects` future-compat lint to a hard error
