Remove Windows GDI specializations for deleteOwnedPtr

We do not need them for many reasons:
- they are not used
- they are not even defined
- they could not work even if they were defined (after r157328)

border-spacing is doubled between table-row-groups.

Every table-section's rows height is calculating separately. So border spacing
had applied to bottom of the first section and top of the second section.

Now, Only Top most section would apply border spacing on top of it's section.
