feat(jest-globals): add Mocked* utility types to jest namespace / object

[mrazauskas]

Summary

From #12424 (comment)

Currently jest object exported from @jest/globals is missing utility types like jest.MockedClass, jest.MockedFunction, which are available from @types/jest. jest-mock already has these types, so let’s try to fix this.

Obstacles:

1. declare namespace jest { is necessary to make this work, but api-extractor is throwing away. Right now I was trying to avoid building @jest/globals, but it should be enough to disable bundling for it. There is just nothing to bundle. (Same with @jest/expect, by the way!)

2. Currently jest-mock has these utility types: Mocked, MockedClass, MockedFunction, MockedObject and I pulled one more from @types/jest – SpiedFunction. Have to write type test to figure out what they all do and if there is no overlap.

(Another obvious overlap is jest.mocked() function. I am not a big fan of it, to be honest (; That’s another topic. Perhaps it is enough to focus on utility types first.)

Test plan

The usual: more type tests and green CI.

@mrazauskas what's the status here? 🙂

EDIT: Oh, #12435 I guess. Same question for that one then, I guess 😀

[mrazauskas]

Good question. I am finishing type tests for Mock Functions (almost there!) and then will move on with refactoring.

Hm.. I did not close this. Had to reset the branch, because there was no need to rebase. I pushed and that’s it. Funny ;D
