imgproc: Optimized remap interpolation #29507 - Add a SIMD dispatch file for remap and vectorize the single-channel (C1) in-bounds paths of bilinear, bicubic and lanczos4 interpolation (32F / 16U / 16S) using width-agnostic gather - Dispatch the bilinear C1 path and drop the per-pixel weight-table gathers - Widen the fixed-point coordinate map conversion - 32F lanczos4 is kept on the scalar path: its vectorized 64-tap accumulation deviates beyond the set float accuracy tolerance - Vectorize the bilinear inlier/outlier run detection so any-channel linear remap skips constant-status runs with SIMD instead of a per-pixel bounds test ### 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
