Note: With this PR, ESLint caching will be automatically enabled when run during next build and next lint, but users have the option to opt-out by running next lint --no-cache.

Many users likely opt-in to caching today using next lint --cache. I kept --cache as a dummy flag so it doesn't cause any breaking changes.
