feat: create @jest/config-utils package

[SimenB]

Summary

Not too happy about the name. Main idea is to colocate both types and utils, since jest-config depends on the world to be able to resolve default dependencies in a pnp context.

This makes it so only jest-circus, jest-jasmine, jest-each and jest-environment* depends on @jest/types.

Fixes #8570

Doesn't it make sense to create @jest/config-types with config types only then?

[SimenB]

The reason I did it this way is so people can reuse some of the helpers without pulling in the massive jest-config, e.g. https://github.com/jest-community/jest-junit/blob/master/utils/replaceRootDirInPath.js. Thoughts?

[thymikee]

Ah I see, we have somewhat similar situation in expect and jest-matcher-utils, right? For some reason I thought we have a generic jest-utils 😅 Then I think it kinda make sense, too bad it has "utils" in name, but I don't have better idea.

[SimenB]

I wondered about creating a @jest/config-normalizer or something which would be what's left in jest-config in this PR and have jest-config be what's in the new util package

Let's circle back later
