QDQ debugger - activations compare (#12544)

Debugger for QDQ loss - activation matching

This is the first part of the QDQ debugger tool: activation matching, where we identify and match corresponding activations from the float model and the qdq model. The idea is that during quantization, we have an original float model and a qdq model. The debugger can run the two models side by side using the same input data. By comparing intermediate activations, we can help the model author figure out where the values differ, and take steps to reduce precision loss.
