Batrachophreno 5277251959 Tool behaviors port (#21663) 
For a robust crafting system, I need a new materials framework.
For a new materials framework, I need to clean up reagents.
To clean up reagents, I need to pare down foods from reagent holders.
To pare down foods from reagent holders, I need to port edibility
components.
To port edibility components, I need to port processing components.
To port processing components, I need to port tool behaviors.

This is all back-end code, no new features or functionality from this.
