FIX: rewrite per-object printing order logic

Browse source 
1. Previous logic can't guarantee left-to-right printing order, so
   toolhead may crash on the right side. In the new algorithm printing
   order is guaranteed.
2. Clearance radius should be the max of 3 directions (left, bottom,
   up), not including right, otherwise collision may happen on bottom or
   up directions.
3. Add is_extrusion_cali_object property to handle extrusion brim
   overlap better.
