Fast entity accessor

We know that using Itementity's Throwertag can save the UUID reference of the entity and access it efficiently:

# 将当前实体的UUID保存到物品NBT中
# 假设我们物品实体的uuid固定为0-0-0-0-1
data modify entity 0-0-0-0-1 Thrower set from entity @s UUID

As long as this entity still exists, we can access this entity through this item anywhere in our data pack:

execute as 0-0-0-0-1 on origin run <命令>

But what if you want to store references to multiple entities? We can let multiple items ride on a world entity and access it with the help of world entity:

# 假设世界实体是0-0-0-0-2
execute as 0-0-0-0-2 on passengers on origin run <命令>

When we want to add a new entity reference, we only need to let a new itemity ride on the world entity without limiting the UUID of the itemity.
