Rollup merge of rust-lang#128174 - compiler-errors:trait-alias-marker, r=oli-obk Don't record trait aliases as marker traits Don't record `#[marker]` on trait aliases, since we use that to check for the (non-presence of) associated types and other things which don't make sense of trait aliases. We already enforce this attr is only applied to a trait. Also do the same for `#[const_trait]`, which we also enforce is only applied to a trait. This is a drive-by change, but also worthwhile just in case. Fixes rust-lang#127222
