[quant][pt2e][refactor] Add input_output_share_observers to node.meta["target_dtype_info"] (#97949)
Summary:
The goal for this PR is to unify the flow of information to reduce fragmentation of implementations between fx graph mode quantization
and quantize_pt2e, since quantize_pt2e will be using node.meta to store this information, we'd like to make sure fx graph mode quantization
get this information from the same place
Test Plan:
python test/test_quantization.py TestQuantizeFx
