Add a Cloudflare Pages build option (again)

We updated our --with-cloudflare build option from Cloudflare Workers to Cloudflare Pages and then back to Cloudflare Pages with Static Assets.

• How does the config file work? What's the difference between using `waku.config.ts` and/or `vite.config.ts`? #763

• Switch back to Cloudflare Workers #944
• Switch from Cloudflare Pages to Workers with Static Assets #989

I found that while Cloudflare Pages' advanced mode function and Cloudflare Workers are almost the same, it seems that Cloudflare Pages' advanced mode function runs after Cloudflare's edge cache while a Cloudflare Worker always runs before the cache. cloudflare/cloudflare-docs#20445

For sites that want to do SWR, it can be better to leverage Cloudflare's cache rules instead of using Cloudflare's cache API from within a worker.

If it's a long-term decision, we could separate two options: ---with-cloudflare-workers and --with-cloudflare-pages
Isn't the plan to integrate Workers and Pages in the future?

And, it depends on how much percentage of waku + cloudflare users need Pages.

Another option is to allow a user-defined deploy adapter.
