In preparation for the upcoming changes in the build system, any parts of the CMake file that are unlikely to be affected should be moved out of the way. This should facilitate an easier resync between the branch 'libpng16' and its successor(s). Specifically: * Move the functions `generate_chk`, `generate_out`, `generate_source` and `generate_copy` to scripts/cmake/PNGGenConfig.cmake. * Move the function `png_add_test` to scripts/cmake/PNGTest.cmake. * Leave the function `create_symlink` in place, but add a TODO note. As we raised the minimum required CMake version to 3.14, we should now be able to use CMake's built-in function instead.
