core: add NEON support for cvFloor in fast_math.hpp #28243 - This PR adds NEON intrinsics-based implementation for the cvFloor function in fast_math.hpp for Windows-ARM64. - Both float and double overloads now use NEON intrinsics for cvFloor Function. - calchist and calchist1d function uses cvFloor function for its computations. - After adding these changes both functions showed improvement in performance. **Performance Benchmarks:** <img width="956" height="273" alt="image" src="https://github.com/user-attachments/assets/a00c98cd-d245-4d11-a9fd-361a3bd89f59" /> 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
