Deprecate `@sveltejs/adapter-cloudflare-workers`

[benmccann]

Describe the problem

It's not very used:
https://npmcharts.com/compare/@sveltejs/adapter-cloudflare,@sveltejs/adapter-cloudflare-workers?log=true&interval=7

However, we probably should wait until the functionality catches up to workers: #10873 (comment)

I hope that this deprecation will be postponed for some time.
The reason is that there is one use case, when you can't use Cloudflare pages.
Time to time we want to embed something into an existing app. And time to time we have no access to server within that APP (some app binded by CNAME).
In that case workers are only a one solution to extend existing router with some new pages. Usually those modifications are pretty simple, but time to time we have to inject some complex apps, ant that sveltekit comes to action.

Our team relies heavily on the workers-adapter tool as part of our process to develop embeddable widgets using sveltekit framework.

Hello
We need to use workers-adapter to build embedables with sveltekit, so I hope it will be possible to use this tool
Thank you!

The two products will be merging over the next year: https://blog.cloudflare.com/pages-and-workers-are-converging-into-one-experience/

We may not be deprecating the adapter after all since Workers will be preferred over Pages #13072 (comment)
