feat(dev): remove boolean option for polyfills

[markdalgleish]

This PR makes a couple of notable changes:

• Removes the boolean option for serverNodeBuiltinsPolyfill, ensuring that there's no serverNodeBuiltinsPolyfill: true in v2 so that we don't need to contie maintaining a canonical server polyfill config.
• Reintroduces "empty" polyfills for fs/fs/promises and crypto modules, matching the earlier behaviour as of Remix v1.17.0 while still allowing consumers to override it.
