Use mesh to deform terrain

[Besjan]

• [ ] Create mesh same resolution as terrain tile and position to max tile height: ProBuilder - GeneratePlane; make it a cube
• [ ] Try cutting the cube with boundary planes
• [ ] Lower mesh vertices close to boundary to terrain level
• [ ] Lower mesh vertices that are out of boundary (check boundary mesh vertex / face normal direction) close to boundary to zero
• [ ] Smooth vertices outside boundary: ProBuilder - Bevel
• [ ] For modified mesh vertices find related terrain vertex and move same as mesh vertex
