Rollup merge of #73300 - crlf0710:crate_level_only_check, r=petrochenkov

Implement crate-level-only lints checking.

This implements a crate_level_only flag on lints, and when it is true, it becomes an error when user tries  to specify this flag upon nodes other than crate node.

This also turns on this flag for all non_ascii_ident lints.
