Add c:fertilizers tag

[ferriarnus]

Add a common tag for fertilizers. Here I mean items that act like bonemeal, by calling the appropriate methods on the bonemealable block.

Alternative suggestion, neoforge:fertilizers tag that when added to, will automatically make the item act like bonemeal due to us patching all the bonemeal checks to check the tag instead

If it's for behavior, I would prefer it be something like neoforge:fertilizes. I have an item that fertilizes stuff, but it itself should not be considered a fertilizer, rather it is a bag that holds fertilizers.

[TelepathicGrunt]

a container that holds another item to use would need its own special implementation. If in neoforge:fertilizes tag and we hook all the bonemeal stuff to use it, your item will get consumed on use if added to the tag as I'm sure in the bonemeal paths, it decrements the itemstack count

[TelepathicGrunt]

Took a look. Bonemealing is not handled by the item but by blocks implementing BonemealableBlock. Then anyone just instanceof check BonemealableBlock and call the bonemealing method on it to grow stuff. So there's no item tag functionality to hook anywhere. Makes sense for this to be a c tag actually.

@ferriarnus did you make issue report on fabric side to see if they are interested?
