CMake: use CMAKE_TOOLCHAIN_FILE 

We should define CMAKE_TOOLCHAIN_FILE (as we are providing Mbed OS toolchain file). This fixes
also the issue we had with Unix makefiles where application would be without response files.

For more details, see https://gitlab.kitware.com/cmake/cmake/-/issues/21104

As the Mbed OS toolchain file is included by CMake, we need to have enabling language in the main CMake (can be executed
only once).
