修复了关于rownum的4个bug。
1.最大值只有255，正常应该是无限大。
2.group by跟where rownum < n同时存在时，禁止将rownum优化成limit
3.groupy by后面没有rownum，而having后面有rownum时，会正常运行，正常应该报错。
4.union前后的子句如果有where rownum < n，并且还有含有order by的子查询时，禁止将order by优化删除掉。

修改create_append_plan函数中对 path为subquery且bestpath->subpaths为空 的情况的处理
参考Gaussdb和Postgres中处理方式，将原有的断言修改为if判断。
当出现上述情况是判断subplan为dummy plan，是则继续执行make_subqueryscan;反之则执行make_result.
