Bjarne Koll b9d3147d3b Use correct placed block position for sound (#12410) 
Previously the server attempted to compute the block placed by using the
BlockPlaceContext. This approach however fails on replacable blocks, as
the BlockPlaceContext computes this during its construction, which
happened after the actual world modification.

The commit reworks this approach and now stores metadata in the
InteractionResult which can later be read.
The diff is structured to allow for easy future expansion of the tracked
metadata.

Subject: [PATCH] Optimize Hoppers
* Removes unnecessary extra calls to .update() that are very expensive
* Lots of itemstack cloning removed. Only clone if the item is actually moved
* Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items.
However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on.
* Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory
* Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration by tracking changes to the event via an internal event implementation.
* Don't check for Entities with Inventories if the block above us is also occluding (not just Inventoried)
* Remove Streams from Item Suck In and restore restore 1.12 AABB checks which is simpler and no voxel allocations (was doing TWO Item Suck ins)
