Fix the duplicated QDQ attributes setup issue (#18039)

### Description
The copied QDQ node should have exactly the same attributes as the
original QDQ node. Otherwise, it might cause errors when the original
node has attributes that use non default values (such as axis != 1
case).

An example user case is like:
A DequantizeLinear node has more than 1 consumer in the graph, and its
attributes axis is 0.

### Motivation and Context
I see the errors like 
#16188 
and this fix could solve the issue.
