Core/Build: Never overwrite the msvc cxx flags in the cache

* Setting all compiler flags in the cache led to circular bloating of
  msvc cxx parameters (was visible in console) which caused MSVC to
  rebuild the whole solution even on a small CMake change.
  It's not neccessary anyway to set the cxx parameters to the cache
  to take effect.
* I'm not sure if the workarround is still needed for MSVC 12+.
* Cleaning the CMake cache is recommended!
* ref #15671
