[Java] Arrow native reader load next batch importing vector from c causing performance degrade

### Describe the bug, including details regarding any error messages, version, and platform.

it seems the native reader is first read the data into c vector, then import it into java format, causing significant performance degrade.

I wonder if it is possible to read directly from c vector ?

### Component(s)

Java

從 Java Arrow native reader 的 load-next-batch 路徑以及回報的效能下降開始。對目前從 C vector 匯入 Java 的流程進行效能分析，並判斷直接讀取是否可行；只有在不變更 reader 結果的情況下取得經測量的改善，才算完成。
