[fix](geo) Fix ST_Contains behavior (#50115)
1. According to the OGC standard, a point lying exactly on the boundary of a polygon no longer returns `true` for `ST_Contains`. This behavior has been changed to return `false`. 2. Fix the inconsistency in `polygon Contains linestring` caused by differing linestring directions. 3. Fixed a logical error in `multipolygon Contains multipolygon`
