Add `$$typeof` brand back to ForwardRefComponent

[jeremybanka]

The recent change to Framer's ForwardRefComponent type breaks compatibility with React.ForwardRefExoticComponent due to a missing property $$typeof, which lives on React.ExoticComponent.

This means that Framer's motion components won't be accepted in contexts calling for a standard ForwardRefExoticComponent. See below:

Working in framer-motion@11.1.3, but breaks in framer-motion@11.1.4

import * as React from "react"
import { motion } from "framer-motion"

function myComponentFactory<P>(component: React.ForwardRefExoticComponent<P>) {
  // implementation
}

myComponentFactory(motion.header) 
/*
❗ Property '$$typeof' is missing in type 'ForwardRefComponent<HTMLElement, HTMLMotionProps<"header">>'
*/

With this change, ForwardRefComponent's type behaves as normal, and can retain the JSX.Element return type while better supporting React's type implementation.
