Fix bugs in checker_detector.cpp after resolving conflicts from PR #3599#3877
### This is the pull request for fixing some bugs in "Color Checker detection"
+ The link to pretrained tensorflow model for detecting Macbeth Color-checker:

#### 1, Detecting color-checker using Neural network
When loading the pretrained Macbeth color-checker detector model, and set it successfully to CCheckerDetector,
```
Ptr<CCheckerDetector> detector = CCheckerDetector::create();
if (!detector->setNet(net))
{
cout << "Loading Model failed: Aborting" << endl;
return 0;
}
```
then
```
if(!detector->process(image, cv::mcc::MCC24, color_checker_roi, 1, true, params)) {
std::cout<<"Color-checker not found\n";
}
Ptr<mcc::CChecker> checker = detector->getBestColorChecker();
Ptr<CCheckerDraw> cdraw = CCheckerDraw::create(checker);
cdraw->draw(image);
```
+ problem 1:
cdraw function failed to draw the correct result due to the following code block failed to update box in checker:
```
for (Ptr<CChecker> checker : checkers){
for (cv::Point2f &corner : checker->getBox())
corner += static_cast<cv::Point2f>(region.tl() + innerRegion.tl());
...
}
```
the corrected and test pass version is:
```
for (Ptr<CChecker>& checker : checkers){
std::vector<cv::Point2f> restore_box;
for (cv::Point2f& corner : checker->getBox()) {
corner += static_cast<cv::Point2f>(region.tl() + innerRegion.tl());
restore_box.emplace_back(corner);
}
checker->setBox(restore_box);
}
...
```

Fix Unused Variable Warning in test_rotation_and_scale_invariance.cpp #3864
### Description:
This PR resolves a warning caused by an unused variable `IMAGE_BIKES` in the file `test_rotation_and_scale_invariance.cpp` within the `xfeatures2d` module of the OpenCV contrib repository.
- **Issue:** The variable `IMAGE_BIKES` was declared but not used in the test file, leading to a compiler warning (`-Wunused-const-variable`).
```
warning: unused variable 'IMAGE_BIKES' [-Wunused-const-variable]
static const char* const IMAGE_BIKES = "detectors_descriptors_evaluation/

Get CUDA code to compile with clang CUDA and without CUDA #3800
Changelist:
- there are some syntactic changes: `<< <` -> `<<<`. For some reason, I do not need to change all those in the code.
- `::min` -> `std::min` in `__host__` code
- `modules/cudaimgproc/src/moments.cpp` needs to have the CUDA code in the `#ifdef`
- The signature of `cv::cuda::swapChannels` is not exactly the same as the C++ one in `modules/cudaimgproc/src/color.cpp`
- `cv::cuda::FarnebackOpticalFlow::create` needs to be explicit about which FarnebackOpticalFlow it returns
