This ensures uniform behavior on any C++11 compliant compiler

- renamed Cascade Lake AVX512_CEL => AVX512_CLX (align with Intel SDE tool)
- fixed CLX instruction sets (no IFMA/VBMI)
- added flag to bypass CPU baseline check: OPENCV_SKIP_CPU_BASELINE_CHECK

    > Size parameter is changed from int to cv::Size type to allow rectangle kernels
    > Kernel creation code is adopted for different kernel sizes to not create only white images on the output

QR-Code detection: accuracy improvement (fixed)

- update optimal solutions on each iteration
