fix(build): Refactor fallback values to be dummy overrides in createEdgeBundle

[sommeeeer]

If you have enableCacheInterception enabled includeCache will be true there, meaning esbuild will potentially bundle aws4fetch and the fallback overrides(sqs-lite, dynamodb-lite & s3-lite) in the middleware handler file. This can happen if you build from the Cloudflare adapter cause the overrides can contain anonymous functions and the override function would return undefined.

To see this your self, build the examples/e2e/app-router in cloudflare repo and look for aws4fetch, sqs-lite etc.. in the middleware handler file. Do we really need to pass any values here tho? I can't find any of them bundled in the middleware handler, even with this fix.

Ok sorry and nevermind all prior message. I read it on my phone and for some reason I thought you removed this line typeof overrides?.[target] === "function"
LGTM Thanks
