[build-utils][cli] Add env vars for VERCEL_PROJECT_SETTINGS_ (#9332)

Browse Source 
This PR adds a few new environment variables for project settings.

This allows frameworks targeting the [Build Output API](https://vercel.com/docs/build-output-api/v3) to read data that is normally only available in through the `config` object when developing a [Builder/Runtime](https://github.com/vercel/vercel/blob/main/DEVELOPING_A_RUNTIME.md).

This will also solve the problem of old Builders/Runtimes that never passed the `config` through to `getNodeVersion()`.
