Changes needed when using oneAPI DPC++ 2025.0

[oleksandr-pavlyk]

It would be nice to add a note for those who attempts to follow the presentation using oneAPI DPC++ 2025.0.0

Changes to MKL FFT interface require updating oneMKL checkout. Updating to the latest revision, we need to take into account that oneMKL library was renamed to oneMath, and -lonemkl should thus be replaced with -lonemath.
