imgproc: Optimized Moments & perf test added - #29393 - Added dispatch for moments (CV_8U, CV_16U, CV_32F and CV_64F) - CV_16S is kept in scalar due to regresssions observed. - Perf test added for meanShift, CamShift and matchShapes. - Extend Moments1 perf coverage to CV_8U alongside 16/32/64-bit depths. ### 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
