Workbench: Option to use Object color

- added `object_color_type` where the user can set if the collection
determines the color, or the object will be used for the color.
Implemented it as an enum as later this can have a random color option.
- moved OB_LIGHTING_* to DNA_view3d_types and renamed it.
- Fixed some DRY in workbench_materials.c. Can remove more DRY's but
will need to discuss the responsibility of the workbench engine as it
might become part of the eevee renderer.
