JNI Lifecycle Fix: Have AdapterStatusListener derive from JavaUplink/DBTNativeDownlink, resolving BTAdapter::removeAllStatusListener() and use shared_ptr_ref<T>

- AdapterStatusListener's native instance is now created at java object construction, etc .. same pattern like BTDevice ..
- Java/Native object relation is inherently thread safe due to using use shared_ptr_ref<T>
