Parse vue 3 emit member to the otions object

[elevatebart]

The problem

In Vue 3 we can use an "emit" member to the options bag to tell parent components what events are available.
It would be a perfect place to gather information about those events (type, description, payload)

https://v3.vuejs.org/guide/component-custom-events.html#validate-emitted-events

Proposed solution

export default {
emits: {
    /**
     * Click on the button
     */
    click: null,

    /**
     * Validate submit event
     * @arg {object} payload
     * @arg {payload.email} String email of the registered user
     * @arg {payload.password} String password of the registered user
     */
    submit: ({ email, password }) => {
      if (email && password) {
        return true
      } else {
        console.warn('Invalid submit event payload!')
        return false
      }
    }
  },
}

There would be typescript support as well.
