[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

首先定位 Java JNI 的 CMake 依赖配置和当前的 Protobuf 设置。检查构建期间如何传递 Protobuf_USE_STATIC_LIBS 和 Protobuf_ROOT，然后验证在没有未记录的手动配置的情况下进行构建；另外确定捆绑协议的安装是否属于范围之内。
