This removes the automatic patching of the global `fetch` function in Server Components environments to dedupe requests using `React.cache`, a behavior that some RSC framework maintainers have objected to. We may revisit this decision in the future, but for now it's not worth the controversy. Frameworks that have already shipped this behavior, like Next.js, can reimplement it in userspace. I considered keeping the implementation in the codebase and disabling it by setting `enableFetchInstrumentation` to `false` everywhere, but since that also disables the tests, it doesn't seem worth it because without test coverage the behavior is likely to drift regardless. We can just revert this PR later if desired.
