core: SIMD optimizations for norm, distance and Hamming APIs (5.x) #29479 - Cache normHamming SIMD impl via a function pointer to cut per-call dispatch cost (improves ORB & BRISK) - Add masked norm and norm-diff SIMD kernels (incl. cn==4 paths) and AVX-512 dispatch for norm/stat - Add brute-force matcher perf test - Alternative port of PR #29335 adapted to the 5.x norm.simd.hpp structure ### 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 - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [x] The feature is well documented and sample code can be built with the project CMake
