Function gen_local_expressions

src/catalog/src/expr_cache.rs:778–788

Generate a random [`LocalExpressions`] value. The returned values are mostly hardcoded and only differ in a single randomized number. That's sufficient for the expr cache tests, since the cache mostly treats expressions as opaque objects.
