[quant][graphmode] Support quantization for `aten::apend` (#40743)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/40743
`aten::append` modifies input inplace and the output is ignored, these ops are not
supported right now, so we'll need to first make `aten::append` non-inplace
by change
```
ignored = aten::append(list, x)
```
to
```
x_list = aten::ListConstruct(x)
result = aten::add(list, x_list)
```
and then quantize the aten::add instead.
