Eevee框架14——EeveeUIFramwork与Addre

本来想用bind直接绑定Addressables的加载代码，无奈异步加载想不出来怎么改写API。

只好重写了EeveeUIFramwork中Page的加载逻辑，适配为Addressables的加载，同时个人感觉同步加载没啥用，直接移除了所有同步加载的API：

    using UnityEngine;
    using System.Collections;
    using System.Collections.Generic;
    using Object = UnityEngine.Object;
    using UnityEngine.AddressableAssets;

这样就可以直接用了，如果没有Addressables的需要自己导入一下，下面是使用demo：
