The Mesh to Grease Pencil conversion would convert every edge into a stroke. This was not the case prior to Blender 4.3. Edges with no branches would be converted into a single stroke instead of mutliple ones. This fix uses `geometry::mesh_to_curve_convert` from geometry nodes to achieve more optimal result with edges connected into one stroke when possible.
