Fix getDisplayInfo() for SurfaceFlinger in HWC2 mode.

#include <unordered_map>

#include <unordered_set>

#include <vector>

#include <map>

namespace android {

    class Fence;

    bool mIsConnected;

    DisplayType mType;

    std::unordered_map<hwc2_layer_t, std::weak_ptr<Layer>> mLayers;

    std::unordered_map<hwc2_config_t, std::shared_ptr<const Config>> mConfigs;

    // The ordering in this map matters, for getConfigs(), when it is

    // converted to a vector

    std::map<hwc2_config_t, std::shared_ptr<const Config>> mConfigs;

};

// Convenience C++ class to access hwc2_device_t Layer functions directly.
