Remove deprecated CMake variable

Browse Source 
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.
