Merge pull request #26061 from penghuiho:fix-pow-bug
Fixed the simd bugs of iPow8u and iPow16u #26061

Add the following cases in opencv_perf_core:

* OCL_PowFixture_iPow.iPow/0, where GetParam() = (640x480, 8UC1)
* OCL_PowFixture_iPow.iPow/2, where GetParam() = (640x480, 16UC1)

iPow8u and iPow16u failed to call to simd accelerating while executing.

Fix the bug by changing the input type of iPow_SIMD function.

Merge pull request #26014 from MaximSmolskiy:increase-search-radius-for-corners-neighbors-in-ChessBoardDetector-findQuadNeighbors
Increase neighbors search radius for corners in ChessBoardDetector:findQuadNeighbors #26014

I didn't do everything right the way I wanted at #25991. I forgot that `edge_len` is edge **squared** length as well as `thresh_scale` is threshold for **squared** scale. So, I wanted to increase scale by `sqrt(2)` times (idea is to use quad diagonal instead of quad side) and therefore `thresh_scale` should be equal to `sqrt(2)^2 = 2`.

And refactor variables names to explicitly indicate that they are squared, so that no one else falls into this trap

I tested this PR with benchmark
```
python3 objdetect_benchmark.py --configuration=generate_run --board_x=7 --path=res_chessboard --synthetic_object=chessboard
```
PR increases detected chessboards number by `1/2%`:

Merge pull request #25968 from FantasqueX:correct-bayer2gray-simd-1
Correct Bayer2Gray u8 SIMD #25968

SIMD version of CV_DESCALE is not correct. It should be implemented using v_dotprod.

What's more, the stop condition of vector operation should be `bayer < bayer_end - 14` because we just need to make sure result is safely stored into `dst`.

pyrDown: offset HAL added, IPP removed #25970

Resolves #25976

### Changes
* HAL added for offset support so that border pixels can be fetched from outside of the image ROI (see `BORDER_ISOLATED` parameter)
* IPP removed since there is `pyrUp` instead of `pyrDown` and there's no easy way to fix this other than rewriting it from scratch
* replaced old C call by modern `cv::pyrDown`

### Pull Request Readiness Checklist

Idea was mentioned in `Section III-B. New Heuristic for Quadrangle Linking` of `Rufli, Martin & Scaramuzza, Davide & Siegwart, Roland. (2008). Automatic Detection of Checkerboards on Blurred and Distorted Images. 2008 IEEE/RSJ International Conference on Intelligent Robots and Systems, IROS. 3121-3126. 10.1109/IROS.2008.4650703` (https://rpg.ifi.uzh.ch/docs/IROS08_scaramuzza_b.pdf):
![Снимок экрана от 2024-08-05 09-51-27](https://github.com/user-attachments/assets/7a090ccc-c24c-4dfb-b0dd-259c8709eb72)
```
* For each candidate pair, focus on the quadrangles they belong to and draw two straight lines passing through the midsections of the respective quadrangle edges (see Fig. 6).
* If the candidate corner and the source corner are on the same side of every of the four straight lines drawn this way (this corresponds to the yellow shaded area in Fig. 6), then the corners are successfully matched.
```

By improving corners matching, we can increase the search radius (`thresh_scale`).

I tested this PR with benchmark
```
python3 objdetect_benchmark.py --configuration=generate_run --board_x=7 --path=res_chessboard --synthetic_object=chessboard
```
PR increases detected chessboards number by `3/7%`:
