AscendC is an extended syntax for the C/C++ language that can be used to
write operators that run on Ascend NPU.

This commit introduce an operator(threshold) written in AscendC. Others
can refer to this to implement other operators.

AscendC can implement efficient fusion operators according to needs, in
this case, threshold execution speed increased by nearly 4 times.

1. remove threshold_opencv_kernel
2. typo ASCENDC_KERNELS_H
3. add ALIGN_UP macro

Enable AscendC kernel operator

Fixes #25081:Latch input corruption fix opencv#3646

Fixes opencv/opencv#25081

As mentioned by WennPaper making it `grayImage = image.clone();` will make a deep copy. It prevents the `InputArray` from being modified.

Documentation transition to fresh Doxygen opencv#3638

Merge with opencv/opencv#25042

…and_infer_test

Add to mcc detect and infer test opencv#3647

merge with opencv/opencv_extra#1153

Added a full pipeline tests:

1. detector->process(img, (TYPECHART)0, 1, true);
2. ColorCorrectionModel model(src, COLORCHECKER_Macbeth); model.run();
3. calibratedImage = model.infer(calibratedImage)*255.;

…tests

- decodemgr.cpp: fix messed: width <--> height
- unicomblock.cpp: fix wrong type at sizeof(...)

as this image appears too difficult, so that test fails on it

…s_and_size

(it may lead to incorrect results if multiple QR found at image)

…code

* rename cv::float16_t to cv::fp16_t

* fp16_t -> hfloat
