derive a delegate class from CHIP, and esp-matter attribute system

[ehsanziyaee]

As we know, to implement appliances, we need to reimplement the delegate class of the CHIP. And through its GetInstance function, we have access to the pointer of its Instance class, so using these APIs makes it impossible to use the ESP-Matter attribute system. Also, according to the story I explained in this issue #1486, two instances of each cluster are created in each endpoint, which causes changes in one instance not to be transferred to the other. Do you have a suggested solution for the first and second cases?

In short, the esp-matter attribute system is only useful for simple clusters, and wherever I use a delegate, it no longer works, and I have to use the APIs of the Server Instance (Cluster) class. Did I understand correctly?
