Support component instance types

[XioDone]

Clear and concise description of the problem

The method exposed by the component, refer to the component in the template, you need to manually import the component in the script, add a type.

const myFormRef = ref<InstanceType<typeof MyForm>>()

<template>
  <MyForm ref="myFormRef"/>
</template>

Suggested solution

Add a switch to option, automatically declare the instance type of a component in components.d.ts

// components.d.ts
export interface GlobalComponents {
  MyForm: typeof import('./components/MyForm.vue')['default']
  MyFormInstance: InstanceType<GlobalComponents['MyForm']>
}

Maybe there's a more elegant way.
