feat: add a hydration binding map

[janechu]

🙋 Feature Request

Any content of certain elements gets modified or rendered by the element, so current hydration comments won't work. This should however be an option so there needs to be a third solution (outside of the standard data-fe-b and inline comments) to track bindings.

List of elements that have issues with inline comments:

• <textarea> - will render the comments
• <style>
• <title> - the browser will escape the comments

💁 Possible Solution

Possibly we can use some kind of map for a web components content.

Example:

<my-component data-fe-b-map="UuWPQ2H"></my-component>
