Auto merge of #13167 - iDawer:exhaustive_patterns, r=Veykril
feat: Implement `feature(exhaustive_patterns)` from unstable Rust

Closes #12753

Recognize Rust's unstable `#![feature(exhaustive_patterns)]` (RFC 1872). Allow omitting visibly uninhabited variants from `match` expressions when the feature is on.

This adjusts match checking to the current implementation of the postponed RFC 1872 in rustc.
