Fix T93388: dropping object on grid in orthogonal view misses the floor plane
`ED_view3d_win_to_3d_on_plane` does not use the `clip_start` and
`clip_end` values of the scene, so the `do_clip` option can be misleading
especially in the orthographic view where the `clip_start` is negative.
For now, don't use the `do_clip` option in orthographic view.
