core: Fix mul32f and addWeighted32f to use native f32 SIMD paths #29413

OpenCV Extra: https://github.com/opencv/opencv_extra/pull/1388

- add 32FC1 coverage to addWeighted benchmark
- avoid intermediate double for f32 variants of scaled multiply and addWeighted.
- Relax AddWeighted 32F test tolerance to match f32 FMA semantics.
