Suspicious virtual destructor in CCBundle3DData.h

[JohnCoconut]

cocos/3d/CCBundle3DData.h has a few structure storing 3D data. But some comes with virtual destructor, some doesn't.

struct ModelData
{
    std::string subMeshId;
    std::string materialId;
    std::vector<std::string> bones;
    std::vector<Mat4>        invBindPose;
    
    virtual ~ModelData()
    {   
        resetData();
    }   
    virtual void resetData()
    {   
        bones.clear();
        invBindPose.clear();
    }   
};

struct MeshDatas
{
    std::vector<MeshData*> meshDatas;
    
    void resetData()
    {
        for(auto& it : meshDatas)
        {
            delete it;
        }
        meshDatas.clear();
    }
    ~MeshDatas()
    {
        resetData();
    }
};  

And no class seems to inherit from struct ModelData. Is it a mistake to include virtual keyword?

@minggo If you think virtual is unnecessary, I will remove it.

Yep, please keep them as game codes may inherit from it.
