feat(localStorage): 增加了用于生成useCookie和storageTime的临时配置作用域的函数scope

BREAKING CHANGE: 移除了 `storageTime` 函数接收 worker 的功能，转而由 `scope`
函数提供类似的服务：

```javascript
G.localStorage.scope({storageTime: "1m", useCookie: true}, function(localStorage) {
  // do something
}, function(localStorage) {
  // do something
})
```
