Preserve naming for inputs/outputs with observer insertion (#18713)

Pull Request resolved: https://github.com/pytorch/pytorch/pull/18713

which mutates the naming for input/output. This is not desired and
required because observer op can be a sync node
- Quantizer is aimed for quantizing tensors so we should insert observer
op for Values that are type tensor
