Auto merge of #13925 - epage:lint-config, r=weihanglo
[beta-1.79] fix(toml): Don't warn on lints.rust.unexpected_cfgs.check-cfg Beta backports: - #13913 (sort of): removes just the lint warning (in a different way to be minimal) so we reduce warning noise for people using this key on nightly In order to make CI pass, the following PRs are also cherry-picked: - #13865 - #13834 (only `time` due to rust-lang/rust#125319) - #13901 - #13931 - #13920 - #13890 - disable link check (not a cherry pick)
