Insert GetAttr for quantization parameters instead of Constant (#30551)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/30551
To enable quantizing with shared types, we need to insert GetAttr nodes for
quantization parameters since the code might be shared by multiple module instances
and we'd like to make quantized module instance also share the same code but with
different values of attributes.
Test Plan:
test_jit.py, test_quantization.py
