a86e9f161d Fix building on OpenBSD 
FAILED: lib/libopencv_core.so.13.0
...
ld: error: undefined symbol: __cxa_atexit

Do not try to use --no-undefined on OpenBSD. OpenBSD does not link
shared libraries with libc and thus linkage with --no-undefined is
expected to fail.

0f1c484ea9 Remove deprecated CMake variable 
CMake variable `CMAKE_COMPILER_IS_CCACHE` is marked as deprecated and "# FIXIT Avoid setting of CMAKE_ variables". It is introduced in https://github.com/opencv/opencv/pull/11167 which is before the release of 4.0. Since it's deprecated almost six years ago, I think it's OK to remove them.

Merge pull request #24286 from ashadrina:intel_icx_compiler_support 
Add Intel® oneAPI DPC++/C++ Compiler (icx) #24286

Intel® C++ Compiler Classic (icc) is deprecated and will be removed in a oneAPI release in the second half of 2023 ([deprecation notice](https://community.intel.com/t5/Intel-oneAPI-IoT-Toolkit/DEPRECATION-NOTICE-Intel-C-Compiler-Classic/m-p/1412267#:~:text=Intel%C2%AE%20C%2B%2B%20Compiler%20Classic%20(icc)%20is%20deprecated%20and%20will,the%20second%20half%20of%202023.)). This commit is intended to add support for the next-generation compiler, Intel® oneAPI DPC++/C++ Compiler (icx) (the documentation for the compiler is available on the [link](https://www.intel.com/content/www/us/en/docs/dpcpp-cpp-compiler/developer-guide-reference/2023-2/overview.html)).
