Summary
Performance "Save map size by not serializing unnecessary item components."
Purpose of change
While debugging #85342 I noticed some excessively large map files. This was due to processed grains storing their entire chain of source items in their components tree. In the given debug save this was ~20% of the entire save.
Describe the solution
Add NUTRIENT_OVERRIDE to a bunch of grain processing items (wheat/barley/buckwheat/corn, to name a few), and then add an additional check to item::io to not de or serialize the components for items with flag_NUTRIENT_OVERRIDE.
Describe alternatives you've considered
Testing
Loaded and saved the large map tile in the linked issue, it shrank a lot (it was a storage shed on a farm with a ton of buckwheat and corn and barley).
