fix(nextjs): adjust generated CSS-in-JS to match latest Next.js recommendations

[jaysoo]

Next.js has compiler options for styled-components and emotion now, so we should generated next.config.js with the latest config. For App Router, the styled-components and styled-jsx usage should also provide custom layout.tsx that uses a registry specific to each styling solution. Emotion support in layout.tsx is pending, but for now users will at least have the compiler: { emotion: true } value added to their next.config.js file.
