Auto merge of #89105 - DevinR528:reachable-fix, r=Nadrieril
Fix: non_exhaustive_omitted_patterns by filtering unstable and doc hidden variants

Fixes: #89042

Now that #86809 has been merged there are cases (std::io::ErrorKind) where unstable feature gated variants were included in warning/error messages when the feature was not turned on. This filters those variants out of the return of `SplitWildcard::new`.

Variants marked `doc(hidden)` are filtered out of the witnesses list in `Usefulness::apply_constructor`.

Probably worth a perf run :shrug: since this area can be sensitive.
