Turbopack: support ignore comments for NFT fs access tracing (#78460)
Support `readFileSync(/* turbopackIgnore: true */ path, 'utf8')` (and same for `path.resolve` and `path.join`) to ignore it during NFT tracing
We already had the infrastructure, just member calls and then specifically the NFT access functions needed to be handled.
Would fix the failing test in https://github.com/vercel/next.js/pull/78358
