Fixes human burgers not naming after the meat donor (#59286)

- Adds custom materials to result of grilling
- Adds custom materials to result of atom processing
- Adds source name and job to mob_meat material if available
- Makes processed atoms have same pixel offsets as their source but randomise with each subsequent one
