Auto merge of #47630 - canndrew:exhaustive-patterns, r=nikomatsakis
Stabilise feature(never_type). Introduce feature(exhaustive_patterns) This stabilizes `!`, removing the feature gate as well as the old defaulting-to-`()` behavior. The pattern exhaustiveness checks which were covered by `feature(never_type)` have been moved behind a new `feature(exhaustive_patterns)` gate.
