Rollup merge of #150934 - move-doc-attr-checks, r=JonathanBrouwer

Browse source 
Move some checks from `check_doc_attrs` directly into `rustc_attr_parsing`

Part of https://github.com/rust-lang/rust/issues/149865.

I also used this opportunity to remove the `id_is_crate_root` method.

Once this is merged, I think I'll try to see if we can remove `target_id` as well.
