Subject: [PATCH] Update OpenCVDownload.cmake to fix log crash

This suppresses the interpretation of string literals by switching the ocv_download_log from a macro to a function.
This avoid crashes when the string to log contains escape characters.

More details about the problem this PR fixes are available at: https://github.com/opencv/opencv_contrib/issues/1131
