Add support for deployment to Cloudflare Pages & Workers

[devarshishimpi]

Describe the feature or enhancement

To start this, I came across this issue created. Yes, Cloudflare does support Next.js. with @cloudflare/next-on-pages for the frontend. And the backend can go to Cloudflare Workers just the way goes to Vercel Functions in case of Vercel deployment.

#1388

I currently use it with Vercel, but kinda curious if there could be support for this as well!
Cloudflare Workers comparatively has limited capabilities and runtime limits. I believe it only supports inbuilt node modules, and a few external npm packages.

If support for the same is being added, docs for the same will also be needed to be created in the website repository.
