kou opened a new issue, #43797: URL: https://github.com/apache/arrow/issues/43797
### Describe the enhancement requested This is another approach of GH-43666. GH-41909 introduced `arrow::ArrayStatitstics` but it's not associated with `arrow::Array`. This issue attaches `arrow::ArrayStatistics` to `arrow::ArrayData`. There was a concern that associated `arrow::ArrayStatistics` may be outdated if `arrow::ArrayData` is mutated after attaching `arrow::ArrayStatistics`. But `arrow::ArrayData` isn't mutable after the first population. So `arrow::ArrayStatistics` will not be outdated. We can require mutators to take responsibility for statistics.
