[quant][graphmode][fx] Add default_replay_qconfig for ops like reshape (#69249)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/69249
This PR added default_replay_qconfig and default_replay_observer which is used
when we want to configure an operator to reuse the observer from input, if the input
Tensor for the operator is not observed, we will not observe the output of this operator either,
if the input Tensor is observed, we will observe the output of the operator with the same observer.
e.g.
```
x1 = x0.reshape()
```
if reshape is configured with default_replay_qconfig:
1. if x0 is observed with observer_0, we'll observe x1 with the same observer instance
2. if x0 is not observed, we won't observe x1 either
Test Plan:
```
python test/test_quantization.py TestQuantizeFx.test_replay_qconfig
```
