Better React 19 support

[chungweileong94]

What's new:

• Update the useFormState example to useActionState from React 19.
• prevState from form action is not undefined type by default.
• Added formData param in form action. As in React 19, <form> will be reset after the action is completed, in that case, we can use the formData to restore the form values, by returning the formData back to the client (Note: Only support in React 19, [Flight] Support FormData from Server to Client facebook/react#28754)
