Review Comment:
Yes, I agree that it can be beneficial, for example if one is only
interested in the null count.
Note that `EncodedStatistics` is [already exposed on
`DataPage`](https://github.com/apache/arrow/blob/7f645d404a16e8c7c939dec70ad61f4ae4de7730/cpp/src/parquet/column_page.h#L68),
so it makes sense to expose it here as well.
A separate improvement would be to make the construction of TypedStatistics
faster, for example creating a decoder instance just to PLAIN-decode one value
does not really make sense. But that's a bit orthogonal IMHO.
