window project over limit clause is not supported

[aceforeverd]

since fdfd1f29c6b0ed46a822afdd459ea17f567ccd66, window project over limit clause is not supported. Because LimitTableHandler is not seekable: https://github.com/4paradigm/OpenMLDB/blob/5ac4667d0e71dc803ddbd04928bc4681b5ba84b6/hybridse/src/vm/catalog_wrapper.h#L444-L448

This kind SQL might not correct.

select id, count(col) over w from (select * from t1 limit 10) window w as (....)

wrongest solution: LimitTableHandler is used for the lazyness of execution. When window iterator is need, a full copy of limited rows are copyed into new TableHandler.

same for

• window (filter)
• join (filter)
