Merge pull request #27717 from MaximSmolskiy:improve_fitellipsedirect_tests 
Improve fitEllipseDirect tests #27717

### Pull Request Readiness Checklist

Previous `fit_and_check_ellipse` implementation was very weak - it only checks that points center lies inside ellipse.
Current implementation `fit_and_check_ellipse` checks that points RMS (Root Mean Square) algebraic distance is quite small. It means that on average points are near boundary of ellipse. Because for points on ellipse algebraic distance is equal to `0` and for points that are close to boundary of ellipse is quite small
