[next] Populate middlewareRawSrc using middleware originalSource (#9602)

Next.js will pass the original middleware matching routes through to the middleware manifest once https://github.com/vercel/next.js/pull/46753 lands. This PR will take those original values and put them in the middleware route `middlewareRawSrc` property.

NOTE: The tests will need to be updated once the Next.js version is updated in the fixtures.
