fix(useWebWorker): IIFE does not pack the @vueuse/shared package in …

[CatsAndMice]

…#2421

Description

• 在文件scripts/rollup.config.ts中，关于iife的设置仅将vue-demi注入了，并没有把shared工具包注入
• 当以cdn链接引入@vueuse/core包时，使用shared工具包提供的方法或常量均为undefined
• 不仅是@vueuse/core，像@vueuse/rxjs也是一样的，如果使用了shared工具包均会报错

例如：
@vueuse/rxjs中提供的useSubscription方法，它需要使用'@vueuse/shared提供的tryOnScopeDispose方法。


执行useSubscription会报错

解决：

• shared工具包也像vue-demi进行注入设置
• 在打包shared工具包自己时，注入操作去除即可
