[Feature] Add workflow to check workflows in .github/workflows/**
Currently we have required job build-and-test for different paths that pull requests affect.
However, we lack the job for changes in workflows path and merges are possible only with admin privileges.
The task is to add the workflow that will contain build-and-test job for changes in .github/workflows/** path.
