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 #127222

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.
