[fuzzer] Add Windows Visual C++ exception intercept

Adds a new option, `handle_winexcept` to try to intercept uncaught
Visual C++ exceptions on Windows. On Linux, such exceptions are handled
implicitly by `std::terminate()` raising `SIBABRT`. This option brings the
Windows behavior in line with Linux.

Unfortunately this exception code is intentionally undocumented, however
has remained stable for the last decade. More information can be found
