  [CMake] Limit -gsplit-dwarf option to C and C++ compilers

Currently, If the C or C++ compiler supports the `-gsplit-dwarf` option it is added to _all_ compilers.
If a project decides to use another  language, such as Swift, this option will be sent to that compiler as well, regardless whether that compiler supports it or not (Swift doesnot).
This patch uses [generator expressions](https://cmake.org/cmake/help/latest/manual/cmake-generator-expressions.7.html) to limit the `-gsplit-dwarf` option to only those compilers that support it (C and C++).
