Added creation of QDQ for TopK node (#25309)
- Added TopK in registry.py so as to create QDQ nodes for the op
- Ensure that both the input and output quantization params are equal
- Added unit test to verify the creation of QDQ nodes for TopK
### Description:
Added support for creation of QDQ nodes for TopK when quantized with ORT static quantization tool
### Motivation and Context:
Currently there is support to form a node unit for TopK operator when QDQ nodes are present and both the input and output quantization params are equal. But there was no support to create QDQ nodes for TopK operator in the ORT static quantization tool
