Modifier: New Weld Modifier

Part of T70240

This is the initial implementation of Weld Modifier.
New features will be added later.

ToDo:
- Seams: restrict welding to vertices along boundary edges.
- Edge Collapse: collapse edges below the length threshold.
- New icon.
- Some customdata are not being correctly interpolated.
