[FEA] Add column constructor from device_uvector&&.

[bdice]

See: #11019 (comment)

We should add a column constructor to be constructible from a device_uvector&& so for outputs like this we can just more conveniently construct a device_uvector<size_type> and then construct the column when returning the output:

rmm::device_uvector<size_type> out_positions{...};
// ...
return make_unique<column>{std::move(out_positions)};

This is the "owning / move semantics" flavor of #10302 / #9621 / #9656. Like those issues/PRs, this is especially helpful when dealing with columns of indices.
