fix: handle wide-character output on Windows console to avoid truncation

[a492219408]

Description

This change fixes a bug where the console would stop printing any subsequent output if it encountered Chinese characters. By converting the wide-string output to UTF-8 with converter.to_bytes(), the console now continues to properly display messages containing Chinese characters without interruption.

What if we change the code to look some thing like this?

void print_device(device_t &device) {
    audio::wstring_t wstring;
    DWORD device_state;

    device->GetState(&device_state);
    device->GetId(&wstring);

    audio::prop_t prop;
    device->OpenPropertyStore(STGM_READ, &prop);

    prop_var_t adapter_friendly_name;
    prop_var_t device_friendly_name;
    prop_var_t device_desc;

    prop->GetValue(PKEY_Device_FriendlyName, &device_friendly_name.prop);
    prop->GetValue(PKEY_DeviceInterface_FriendlyName, &adapter_friendly_name.prop);
    prop->GetValue(PKEY_Device_DeviceDesc, &device_desc.prop);

    if (!(device_state & device_state_filter)) {
      return;
    }

    std::string device_state_string = "Unknown"s;
    switch (device_state) {
      case DEVICE_STATE_ACTIVE:
        device_state_string = "Active"s;
        break;
      case DEVICE_STATE_DISABLED:
        device_state_string = "Disabled"s;
        break;
      case DEVICE_STATE_UNPLUGGED:
        device_state_string = "Unplugged"s;
        break;
      case DEVICE_STATE_NOTPRESENT:
        device_state_string = "Not present"s;
        break;
    }

    std::string current_format = "Unknown"s;
    for (const auto &format : formats) {
      // This will fail for any format that's not the mix format for this device,
      // so we can take the first match as the current format to display.
      auto audio_client = make_audio_client(device, format);
      if (audio_client) {
        current_format = format.name.data();
        break;
      }
    }

    std::cout
      << "===== Device ====="sv << std::endl
      << "Device ID          : "sv << platf::to_utf8(wstring.get()) << std::endl
      << "Device name        : "sv << platf::to_utf8(no_null((LPWSTR) device_friendly_name.prop.pszVal)) << std::endl
      << "Adapter name       : "sv << platf::to_utf8(no_null((LPWSTR) adapter_friendly_name.prop.pszVal)) << std::endl
      << "Device description : "sv << platf::to_utf8(no_null((LPWSTR) device_desc.prop.pszVal)) << std::endl
      << "Device state       : "sv << device_state_string << std::endl
      << "Current format     : "sv << current_format << std::endl
      << std::endl;
  }

where the platf::to_utf8 is from https://github.com/LizardByte/Sunshine/blob/master/src/platform/windows/misc.h#L35? Getting rid of the static std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>, wchar_t> converter; and std::wcout altogether.

I have not checked if it compiles, but please do try it out.
