Merge pull request #25970 from savuor:rv/hal_pyrdown 
pyrDown: offset HAL added, IPP removed #25970

Resolves #25976

### Changes
* HAL added for offset support so that border pixels can be fetched from outside of the image ROI (see `BORDER_ISOLATED` parameter)
* IPP removed since there is `pyrUp` instead of `pyrDown` and there's no easy way to fix this other than rewriting it from scratch
* replaced old C call by modern `cv::pyrDown`
