[Java][JNI] Improve current cmake java libraries dependencies that needs Protobuf_ROOT and Protobuf_USE_STATIC_LIBS variables

### Describe the enhancement requested

The current Java JNI build needs to declare these CMAKE variables in order to build correctly:

- -DProtobuf_USE_STATIC_LIBS=ON
- -DProtobuf_ROOT=${project.basedir}/../cpp-jni/protobuf_ep-install

It may be possible to add support for installing bundled protocols.

### Component(s)

Documentation, Java

先定位 Java JNI 的 CMake 相依性設定與目前的 Protobuf 設定。檢查建置期間如何傳遞 Protobuf_USE_STATIC_LIBS 與 Protobuf_ROOT，接著驗證在沒有未記錄的手動設定下進行建置；另外判定隨附協定的安裝是否屬於範圍。
