Implemented a check to enable instrumentation for IPP HAL #29542 To enable instrumentation for IPP HAL correctly it needed to generalize a part of `private.hpp` and put it to the separate file that can be included in `private.hpp` and `ipp_utils.hpp` both to avoid duplication. Built with `-DENABLE_INSTRUMENTATION=ON` and ran `opencv_perf_imgproc --perf_instrument=1`: | Test | IPP weight before | IPP weight after | |---|---|---| | `distanceTransform` (8U->32F) | 0.0% | ~76% | | `ippSobel` | 0.0% | ~98% | | `scharrViaSobelFilter` | 0.0% | ~90% | ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [ ] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake
