Steps to reproduce

1. ref type of component is incorrect
   According to vue official guide, we should use typeof SomeComponent for GlobalComponents interface. But if we do so, the ref type is incorrect as it should be VueElement

Also, the event parameter is wrong, it should be CustomEvent<number>

2. ReturnType of defineCustomElement is incorrect
   We can see events are included in the type, but similarly the event parameter is wrong. Also, having onXXX in type may lead to wrong usage like below (But it's needed for JSX, I'm not sure about this)

// expect error, but not
el1.value.onUpdate = (val) => alert(val)

Besides, the ReturnType doesn't include $props and $emit, which are needed for vue template type inference, so we can see there is no autocompletion for both props and events
I think VueElementConstructor should include that like in official guide does, so that we can directly use that type for GlobalComponents

What is expected?

Typescript should work well.
I think we can fix defineCustomElement, and use its return type for GlobalComponents instead of using typeof VueComponent, and then update the official doc

What is actually happening?

Not working well
