ts: refactor OpenCV tests - removed tr1 usage (dropped in C++17) - moved includes of vector/map/iostream/limits into ts.hpp - require opencv_test + anonymous namespace (added compile check) - fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions - added missing license headers

Merge pull request #25842 from mshabunin:cpp-imgproc-test-4.x imgproc: remove C-API usage from tests #25842 Final cleanup will be done in 5.x after regular merge. Some tests have been reworked, some required only slight modifications.
