Summary:
This is a follow up to https://github.com/pytorch/pytorch/pull/118605 to remove `fold_quantize` flag from
`convert_pt2e`
Test Plan: CI
Differential Revision: D53247301
BC Breaking Note:
flag `fold_quantize` set to True `convert_pt2e` and now we'll fold the quantize op in the weight by default, so users will see model size reduction by default after pt2e quantization.
2.2
```
folded_model = convert_pt2e(model, fold_quantize=True)
non_folded_model = convert_pt2e(model)
```
2.3
```
folded_model = convert_pt2e(model)
non_folded_model = convert_pt2e(model, fold_quantize=False)
```

This is a lot of files changed! Don't panic! Here's how it works:
* Previously, we set `follow_imports = silent` for our mypy.ini configuration. Per https://mypy.readthedocs.io/en/stable/running_mypy.html#follow-imports, what this does is whenever we have an import to a module which is not listed as a file to be typechecked in mypy, we typecheck it as normal but suppress all errors that occurred in that file.
* When mypy is run inside lintrunner, the list of files is precisely the files covered by the glob in lintrunner.toml, but with files in excludes excluded.
* The top-level directive `# mypy: ignore-errors` instructs mypy to typecheck the file as normal, but ignore all errors.
* Therefore, it should be equivalent to set `follow_imports = normal`, if we put `# mypy: ignore-errors` on all files that were previously excluded from the file list.
* Having done this, we can remove the exclude list from .lintrunner.toml, since excluding a file from typechecking is baked into the files themselves.
* torch/_dynamo and torch/_inductor were previously in the exclude list, because they were covered by MYPYINDUCTOR. It is not OK to mark these as `# mypy: ignore-errors` as this will impede typechecking on the alternate configuration. So they are temporarily being checked twice, but I am suppressing the errors in these files as the configurations are not quite the same. I plan to unify the configurations so this is only a temporary state.
* There were some straggler type errors after these changes somehow, so I fixed them as needed. There weren't that many.
In the future, to start type checking a file, just remove the ignore-errors directive from the top of the file.
The codemod was done with this script authored by GPT-4:
```
import glob
exclude_patterns = [
...
]
for pattern in exclude_patterns:
for filepath in glob.glob(pattern, recursive=True):
if filepath.endswith('.py'):
with open(filepath, 'r+') as f:
content = f.read()
f.seek(0, 0)
f.write('# mypy: ignore-errors\n\n' + content)
```

Summary:
Changes the PNP test cases to use QNNPACK. The only reason is because
I'm switching to Mac M1 as my primary machine, which supports QNNPACK
but not fbgemm, and it's convenient for me to be able to run these
locally.
PNP itself is not backend specific, so it does not matter which backend
the functionality is tested on.

Summary: This PR removes the is_reference flag from the existing
convert_fx API and replaces it with a new convert_to_reference
function. This separates (1) converting the prepared model to a
reference model from (2) lowering the reference model to a quantized
model, enabling users to call their custom lowering function for
custom backends. For the native fbgemm backend, for example, the
following are equivalent:
```
from torch.ao.quantization.quantize_fx import prepare_fx, convert_fx
prepared = prepare_fx(model, ...)
quantized = convert_fx(prepared, ...)
```
```
from torch.ao.quantization.fx import lower_to_fbgemm
from torch.ao.quantization.quantize_fx import (
prepare_fx,
convert_to_reference
)
prepared = prepare_fx(model, ...)
reference = convert_to_reference(prepared, ...)
quantized = lower_to_fbgemm(reference, ...)
```
Note that currently `lower_to_fbgemm` takes in two other arguments
that are difficult for users to provide. A future commit will remove
these arguments to make the helper function more user friendly.

Following https://github.com/pytorch/pytorch/pull/78452,
this commit replaces the following config dicts with python objects:
- prepare_custom_config_dict -> PrepareCustomConfig
- convert_custom_config_dict -> ConvertCustomConfig
- fuse_custom_config_dict -> FuseCustomConfig
This leads to better type safety and better user experience in
notebook settings due to improved auto completion. The new APIs
are as follows:
```
from torch.ao.quantization.fx.custom_config import PrepareCustomConfig
prepare_custom_config = PrepareCustomConfig() \
.set_float_to_observed_mapping(float_class, observed_class) \
.set_non_traceable_module_names(["mod1", "mod2"]) \
.set_non_traceable_module_classes([class1, class2]) \
.set_input_quantized_indexes([0, 1]) \
.set_output_quantized_indexes([0]) \
.set_preserved_attributes(["attr1", "attr2"])
convert_custom_config = ConvertCustomConfig() \
.set_observed_to_quantized_mapping(observed_class, quantized_class) \
.set_preserved_attributes(["attr1", "attr2"])
model = prepare_fx(
model,
qconfig_mapping,
example_inputs,
prepare_custom_config=prepare_custom_config)
model(data)
model = convert_fx(model, convert_custom_config=convert_custom_config)
```
For backwards compatibility, prepare_fx, prepare_qat_fx, and
convert_fx will continue to accept Dicts, which will be converted
to the relevant *CustomConfig object internally.
Note that this commit does not modify existing tests to use the
new API; they will continue to pass in Dicts as before, which still
works but triggers a deprecation warning. This will be handled in
a future commit.

This PR introduces 3 BC changes:
First, this PR propagates `BUILD_CAFFE2` flag to `libtorch` and `libtorch_python`, which is necessary for non-caffe2 ONNX runtimes when using `ONNX_ATEN_FALLBACK` operator export type.
Second, as a complement of https://github.com/pytorch/pytorch/pull/68490, this PR refactors Caffe2's Aten ops symbolics to consider not only the `operator_export_type` (aka `ONNX_ATEN_FALLBACK`) to emit Caffe2 Aten ops, but also whether `BUILD_CAFFE2` (which is called `torch.onnx._CAFFE2_ATEN_FALLBACK` in python binding) is set.
Lastly, it renames `onnx::ATen` to `aten::ATen` for ONNX spec consistency in a BC fashion.
ONNX doesn't have `ATen` op on its spec, but PyTorch ONNX converter emits them. Non-Caffe2 backend engines would be mislead by such operator's name/domain. A non-ideal workaround would be to have Aten ops handled based on its name and ignore the (non-complaint) domain. Moreover, users could incorrectly file bugs to either ONNX or ONNX Runtime when they inspect the model and notice the presence of an unspecified ONNX operator.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73863
This PR fully aligns the convert function with the design: https://github.com/pytorch/rfcs/blob/master/RFC-0019-Extending-PyTorch-Quantization-to-Custom-Backends.md
and simplifies the implementation of convert function by always produce a reference quantized model (with reference patterns) first,
and then lower the model to a quantized model that is runnable with PyTorch native backend (fbgemm/qnnpack).
This PR makes the convert.py much easier to understand than the previous implementation, and we are able to remove majority of code
in quantization_patterns.py as well (in followup PRs).
