refactor: Store item data in ScriptableObject

Is your feature request related to a specific issue? Please describe.
The current project uses a text file to define items and relies on an ID-based system to access item-related functionality. This should be refactored to store item data using ScriptableObjects.

Describe the solution you'd like

1. Deprecate the old item system.
2. Add an item class that inherits from ScriptableObject.
3. Update all content related to the old item system to be associated with the new item class.

Describe alternatives you've considered
None so far.

Additional context
None so far.

refactor: 将item数据存储在ScriptableObject中

您的功能需求是否与某个问题相关？请描述
目前项目内使用的是txt文本设置 item + 通过 id 获取 item 的方式来运行所有与 item 相关的功能。
这应当被重构为通过 ScriptableObject 存储 item 数据。

描述您希望的解决方案

1. 废弃旧的 item 系统。
2. 添加继承自 ScriptableObject 的 item 类。
3. 将所有与 旧 item 系统 相关联的内容改为与新 item 类关联。
