Update demo files for Godot 4.2.1 (#1013)

All demos were opened with Godot 4.2.1, with the mesh format
upgraded for 3D demos.

The 3D antialiasing demo now uses Extra Cull Margin on the last
object to prevent it from disappearing too early when the camera
rotates (due to its use of shader-based animation).
