[quant][graphmode][fx] qconfig_dict support more types of configurations (#44856)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/44856
Support following format of qconfig_dict
```python
qconfig_dict = {
# optional, global config
"": qconfig?,
# optional, used for module and function types
# could also be split into module_types and function_types if we prefer
"object_type": [
(nn.Conv2d, qconfig?),
(F.add, qconfig?),
...,
],
# optional, used for module names
"module_name": [
("foo.bar", qconfig?)
...,
],
# optional, matched in order, first match takes precedence
"module_name_regex": [
("foo.*bar.*conv[0-9]+", qconfig?)
...,
]
# priority (in increasing order): global, object_type, module_name_regex, module_name
# qconfig == None means fusion and quantization should be skipped for anything
# matching the rule
}
```
