Implements crafting with the survival inventory crafting grid. This does not implement a crafting table as those UIs have not been implemented yet. However, functionality to get a recipe from a 3x3 crafting grid does exist (ferrumc_core::crafting::get_recipes_from_3x3) so crafting tables should be fairly simple to implement once we get there.

When the survival crafting grid is updated, the code will search through recipes to find ones that match the current grid. If one is found, it will update the output to reflect that.

To make this work I had to implement basic inventory syncing. My code just assumes that the client is telling the truth and updates the player's inventory in whatever way the client tells it to. While for now this is fine, when we implement other containers (or even just the player inventory better) we want to ensure that changes are valid. Additionally, the crafting grid just gets cleared when the player closes their inventory. Again, this should be changed in later implementations of the inventory.

This PR does NOT add recipe searching functions for any other crafting type (smelting, blasting, campfire cooking, smithing, etc). It only implements the player's survival crafting grid (with the aforementioned functionality to support 3x3 grids).

If this PR gets merged I'm going to open issues for the inventory syncing problem so if someone else wants to tackle it, they can.
