Windows: Added `/EHsc` to `CMAKE_CXX_FLAGS`.

After upgrading Visual Studio to 15.5.2, warning C4530 started being
emitted for practically every file. Since we use the STL (which uses
exceptions), apparently we need to compile with `/EHsc`. This sets the
exception-handling model to catch C++ exceptions, and to assume that
functions declared as `extern "C"` never throw a C++ exception.
