### Rationale for this change This is a follow up of https://github.com/apache/arrow/pull/34611 (thanks @sunchao) We should set `valueCount` when loading `NullVector`. Unfortunately there's no `nullCount` field. ### What changes are included in this PR? * `valueCount` added to NullVector * `name` added to NullVector's TransferPair ### Are these changes tested? Yes. unit tested. ### Are there any user-facing changes? Yes, a NullVector with a non-null name will maintain the name when transferred via `TransferPair` instead of defaulting to the default name `$data$`. -- This is an automated message from the Apache Git Service.
