Fix T94672: incorrect Workbench shadows with GPU subdivision

The `lines_adjacency` IBO build in the GPU subdivision case was missing
edges at the boundaries of open meshes. As it is used for the shadow
pass, the shadows were then not clipped properly.

This would also make X-Ray mode render differently in those cases.

To fix this, we can simply reuse the buffer finalization routine from the
non-subdivision case, as such edges are handled there.
