test(nextjs): Add vinext e2e tests

vinext builds a Next.js app with Vite. Its e2e tests run in two places:

- nextjs-16 gets the optional variants `nextjs-16 (vinext)` and
  `nextjs-16 (vinext, bun)`. vinext builds the same app, and the same tests
  run as for Next.js. They skip the checks of the Next.js build output, and
  what vinext can not do yet: `openai` and `ioredis` get their diagnostics
  channels from the build-time loader of webpack or Turbopack, which vinext
  does not run, and without a Sentry build plugin there is no component
  annotation and no module metadata for the third-party filter. The OpenNext
  wrangler config is now `wrangler.opennext.jsonc`, because vinext refuses to
  build without the Cloudflare plugin when the project root has a wrangler
  config.
- `vinext-cf-workers` covers vinext on Workers. Its Worker entry has no
  Sentry calls, so `sentryCloudflareVitePlugin` must wrap it with
  `withSentry` from `@sentry/nextjs/cloudflare`. The app also has the server
  config of a Next.js app, whose `init` must create no second client in the
  Worker. The tests check that each request has one `http.server` span with
  the route of Next.js and the Next.js spans in its segment, that an incoming
  trace is continued in that segment, and that an error from
  `onRequestError` is in the trace of the request.

There is no Deno variant. On Deno, the `node:http` server of vinext starts
each request after the first one in the AsyncLocalStorage store of an
earlier request, also without Sentry, so vinext creates no request span.

+- **Build flavors**: a variant can also build the same app with another tool, for example `nextjs-16 (vinext)` builds

 - **Runtime-specific files**: a file that has the runtime as a part of its name replaces the existing file without that
   part, for example `app/entry.server.cloudflare.tsx` replaces `app/entry.server.tsx` and `vite.cloudflare.config.ts`
