Describe the feature

Hello there. I've been digging around and found this new preprocessorMaxWorkers setting from Vite, which is considered experimental. I have tried to enable it for our project and build time reduced by almost 30 seconds.

I've come with idea to enable this for all Nuxt users and allow to easy configure it from experimental:

• Name in config: experimental.preprocessorMaxWorkers
• Default: true (or maybe false until next minor?)
• Possible values: boolean | number
• Basically enables vite.css.preprocessorMaxWorkers

I can see that as potential performance improvement with option for easy disable.

I would happily implement that if Nuxt team is OK with described above.
