Fix ambiguous overload, wxScopedCharBuffer comparison, and wxArrayString ctor

- PhysicalPrinterDialog: disambiguate set_values() call with explicit
  std::vector<std::string> (wxArrayString now also matches initializer list)
- Preferences: use ToStdString() instead of mb_str() for std::string comparison
- Plater: use wxString::FromUTF8() for wxArrayString constructor argument
