feat(types): better compatibility

[posva]

I think It would make sense to expose DebuggerEvent, VNode, and Plugin types to make them compatible with Vue 3. I'm not sure if types should be exposed individually or if there should be an export *.

Other types that I think should be added:

• ComponentCustomProps
• AllowedComponentProps
• VNodeProps

There are useful for solar:

// example from vue-router-next (which doesn't require this as it is Vue 3 only)
export const RouterView = RouterViewImpl as unknown as {
  new (): {
    $props: AllowedComponentProps &
      ComponentCustomProps &
      VNodeProps &
      RouterViewProps

    $slots: {
      default: (arg: {
        Component: VNode
        route: RouteLocationNormalizedLoaded
      }) => VNode[]
    }
  }
}
