Cleanup: Move impl of #[rustc_dump_object_lifetime_defaults]

[fmease]

Module rustc_passes::check_attr hosts validity checks for attributes (that can't be impl'ed in rustc_attr_parsing (yet)). However on main, the actual impl of #[rustc_dump_object_lifetime_defaults] lives there, too, which is wrong. Move it closer to the provider of the corresponding query (object_lifetime_defaults) which lives in rustc_hir_analysis. IIRC the eventual goal is to remove check_attr entirely in favor of rustc_attr_parsing if possible, meaning the impl probably has to move in the future anyway. Let's do it now.
