Check threshold only for changed files

[7rulnik]

Summary

Currently if we use findRelatedTests jest will check thresholds for every group from coverageThreshold. So it always fails and it's impossible to run tests only for changed files on CI for example.

This fix filters thresholdGroups by files from coveredFilesSortedIntoThresholdGroup if findRelatedTests set and checks only filtered groups.

If it looks good, I will add tests and changelog entry.

Also we can add same logic for all changes-related options: --onlyChanged, --changedFilesWithAncestor, --changedSince.

Test plan

Add coverageThreshold in jest config

  coverageThreshold: {
    'packages/jest-each': {
      branches: 100,
    },
  }

and then run some tests with coverage not related to one in threshold configuration. For example: yarn jest --findRelatedTests packages/jest-snapshot/src/dedentLines.ts --coverage --collectCoverageFrom packages/jest-snapshot/src/dedentLines.ts (collectCoverageFrom is required beacuse of #10083 issue). It should pass

I'm sorry this was left lying around so long until I found it in my inbox 😬
This looks good to me - obviously a run with findRelatedTests is stilly likely to produce lower coverage and thus miss the coverage target, but with this it may in some cases hit the thresholds...
If you add test and changelog I'd merge :)

Wow! I almost forgot about this PR. Yeah, for sure, will try to find some time on this or next week.

What about other's changed-related flags?
