Mark Functional components in DOM so thay can be displayed in vue developer console

[1099511627776]

What problem does this feature solve?

Functional components will be displayable and debugable in vue developer console

What does the proposed API look like?

1. Add additional property vue_func to HTMLelement that contains object with basic information about functional component (e.g. context, props etc).
2. Property from 1 will be scanned with vue developer tools and displayed

Support for functional components is already in the making AFAIK. It has been mentioned in Vue.js Sprint summary lately.

I believe this is already tracked by @Akryum somewhere else. @Akryum reopen if you really want to track this in both sides 🙂

In devtools 5.0 functional components are displayed. We just need to merge #8586 to be able to display their props.
