Rollup merge of #121202 - Urgau:check-cfg-limit-diagnostics, r=pnkfelix
Limit the number of names and values in check-cfg diagnostics The Rust for Linux [feedback](https://github.com/rust-lang/rust/issues/82450#issuecomment-1947462977) to the check-cfg Call for Testing, revealed a weakness in the check-cfg. They are unbounded and in the case RfL they have ~20k cfgs and having them printed (even once) is unbearable. This PR limits it to 35 (28 rustc well known + `feature` + `docsrs` + 5 custom) which feels like a good middle ground for regular users (i.e. Cargo users). When it goes over that limit print the N first with " and X more". ``@rustbot`` label +F-check-cfg
