Do not always propagate linker language preference
The commit "Consider link dependencies for link language" taught CMake to propagate linker language preference from languages compiled into libraries linked by a target. It turns out this should only be done for some languages, such as C++, because normally the language of the program entry point (main) should be used. We introduce variable CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES to tell CMake whether a language should propagate its linker preference across targets. Currently it is true only for C++.
