Add missing `target_feature` to the list of well known cfg names

This PR adds the missing `target_feature` cfg name to the list of well known cfg names.

It was notice missing in https://github.com/rust-lang/rust/issues/96472 thanks to `@bjorn3,` the reason being that `--check-cfg=names()` automatically inherit the names passed by `--cfg` (or internal to `rustc`) and is seems that the vast majority of targets have at least one target feature leading to `target_feature` being a well known name in most target but it should always be a well known name so this PR add it unconditionally to list.
