Closes NEXT-2146
Improve styled-jsx types in next.js, previously there's no `declare module` for styled-jsx and there's type name conflicts in `styled-jsx/index.d.ts` and we use a rename hack to avoid the conflicts. Now styled-jsx 5.0.3 fixed those issues.

This PR introduces a new experimental component, `next/future/image`, which is inspired by the existing experimental `layout="raw"`.
The difference is that much of the code has been deleted in order to reduce client-side code as well as reduce complexity:
- No `layout` prop
- No `loader` config (although `loader` prop works)
- No `IntersectionObserver`, use native `loading="lazy"`
- No `lazyBoundary`
- No `lazyRoot`
- No `fill` (yet) so width & height are required
- No `objectFit` (use `style` instead)
- No `objectPosition` (use `style` instead)
This improves performance because native `loading="lazy"` doesn't need to wait for React Hydration and client-side JS.
In a future PR, we will modify `next/image` to remove `layout="raw"` since this new component supersedes it.
