feat: createApp support lifetimes hooks about core

[LinusBorg]

import { creatApp, h } from 'vue'
import App from 'App.vue'

const app = createApp({
  onMounted() {
    // do what you need here
  },
  render: () =>  h(App)
})

@LinusBorg，This is a solution I didn't expect, thanks, but I have one more question。

when mounted, mount(div), the div children don't have element

[LinusBorg]

That would depend on the implementation of that component. Seems that it rendered nothing, maybe because of a v-if? I cant tell without seeing it

It’s pure html without any js logic.

I will give you a warehouse address later. Are you interested in helping track it down?

[LinusBorg]

Have you checked that cur.component is actually containing the component at the moment of rendering?
