[2/n] no-context lint: migrate some crates (vercel/turborepo#5640)

This migrates some crates away from using `context`, specifically:

- `node-file-trace`
- `turbo-tasks-build`
- `turbo-tasks-fetch`
- `turbo-tasks`
- `turbopack-build`
- `turbopack-cli-utils`
- `turbopack-cli`
- `turbopack-core`
- `turbopack-ecmascript`

This also moves the lint to `error` and ignores other failing crates.
