Refactoring GitHub Actions related to pytest

[drew2a]

This PR eliminates the profiler option that was introduced in #7135. At the time, the feature was added to identify tests that were causing timeouts during test suite execution. However, in reality, this option has never assisted us in pinpointing the actual issues.

Given that it's simpler to run the profiler on a local machine, I have decided to remove it from our GitHub Actions. This action is aimed at maintaining relative simplicity in our workflows.

Another update involves the operating system-related separation of pytest arguments. This change will facilitate the reinstatement of the xdist feature, complete with all of the fixes @kozlovsky contributed in #6176.

As an option, instead of writing

      - name: Run Pytest (Win)
        if: runner.os == 'Windows'
        run: |
          pytest ${PYTEST_CORE_ARGUMENTS_WIN}

      - name: Run Pytest (Linux)
        if: runner.os == 'Linux'
        run: |
          pytest ${PYTEST_CORE_ARGUMENTS_LINUX}

      - name: Run Pytest (Mac)
        if: runner.os == 'macOS'
        run: |
          pytest ${PYTEST_CORE_ARGUMENTS_MAC}

      - name: Run Tunnels Tests (Win)
        if: runner.os == 'Windows'
        run: |
          pytest ${PYTEST_TUNNELS_ARGUMENTS_WIN}

      - name: Run Tunnels Tests (Linux)
