Move implementation of MakeBoxes for Graphics and Graphics3d to mathics.format.box

[mmatera]

This PR starts to reorganize the code for formatting Graphics and Graphics3D expressions according to the new organization. Also

• Following the scheme in Layout boxes, default values of Options in GraphicsBox and Graphics3DBox expressions are not shown.
• Fix render 3DBoxes including many points (example: Sphere[{pt1, pt2,...}]).
