fix: Add a common check to use as a required check

[mikolaj-krzyzanowski-f3]

What problem does this PR solve?

• Currently, with a large matrix job and several optional tests there are not good required checks for PRs as they can often be skipped.
• This PR allows setting a single required check that alongside a few other required checks ensures the tests either run when needed or are skipped when not and the PRs are correctly blocked in both cases if there is an issue with the checks.

What's changed and how it works?

• The single job will verify that required jobs have succeeded and the optional ones either succeeded or were skipped, which happens when their conditions are not fulfilled and is expected for some PRs.
• Adding a few other jobs to required checks means there shouldn't be a scenario where jobs that are supposed to run were skipped or failed and the PR is mergeable.
