Backport #26271 by @lunny This PR will fix #26264, caused by #23911. The package configuration derive is totally wrong when storage type is local in that PR. This PR fixed the inherit logic when storage type is local with some unit tests. Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
