all_tile_entities() and tile_entity_type addition?

CMDHELPER-3146 - Reported by Raven0

Any possibility for these to be added, at least just for grabbing info? Better than to scan full chunk to see if X tile entity(like spawner,dispenser, dropper etc) is in it.

Should function same as all_entities() and entity_type() functions, only you would get list of tile entities in the first one, and by using it's ID(if all_tile_entities() would return that), you get it's type in other function.

getTileEntities() method already exists in spigot API, but not really sure about others.

Related spigot libraries:
Chunk: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Chunk.html
BlockState: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/BlockState.html

首先阅读现有的 all_entities() 和 entity_type() 函数，然后检查所引用的 Spigot Chunk.getTileEntities() 和 BlockState API。在实现类似函数之前，明确 tile-entity ID 和类型应如何表示；当行为已定义并由相关项目测试覆盖时即完成。
