vite打包会引入未使用的组件，该组件使用defineComponent包裹

[luoyi58624]

Describe the bug

1.这是使用vite库模式打包出来的es代码，分别导出一个简单组件和函数

2.然后app.vue使用hello函数

3.最后打包

tip：若删除defineComponent，vite则不会将该组件打包进来！

add /*#__pure__*/ annotation to defineComponent, it work.

@vitejs/plugin-vue-jsx only transform jsx. may be it can automatically
add /*#__pure__*/ to jsx or tsx ?
