Title: gpuarithm module refactoring

* Switched to Input/Output Array.
* Converted gpu::LUT function into Algorithm:
* implementation differs for different NPP versions;
* implementation requires some preprocessing steps and additional buffers;
* with new API all this implementation details are hidden;
* old API still can be used for source compatibility (marked as deprecated).
* Converted gpu::convolve function into Algorithm to hide implementation details:
