[Vectorized Reader] Add attributes in ColumnVector and RowBatch

As discussed in HIVE-8128, we want to add some attributes in vector.

- In `ColumnVector`, add two attributes: one is `boolean noNulls`, which indicates whether the whole column vector has no null value. The other is `boolean isRepeating`, which indicates whether the same value repeats for whole column vector. They could be calculated at the same time when we read a vector. SQL engines (like Hive) can check these attribute to skip some values.
- In `RowBatch`, add one attribute `int size`, which indicates the number of rows in this batch. This is just for easy usage. Its value should be the same as `RowBatch.columns\[0\].numValues`.

まず ColumnVector、RowBatch、およびベクトル化された reader の実装を特定します。ベクトルとバッチがどこで設定されるかを追跡し、その後、noNulls、isRepeating、size が記載されたセマンティクスと一致していること、さらに既存の reader テストが結果のメタデータをカバーしていることを確認します。
