[quant][fx] Make scale, zero_point buffers in the model, use FQN (for quantize_per_tensor ops) (#51171) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/51171 Following up on previous PR, this PR makes scale and zero_point for quantize_per_tensor to be registered as buffers in the module. Currently the dtype is still stored as attr (not registered as buffer) since we can only register tensor types.
