8cb68b136f Proper modeling of recursive types (#142300)
Currently there are a few type annotations that falsely state that mypy doesn't support recursive types.

Recursive type support is available in mypy for a few years already. It has been officially enabled in [version 0.991](https://mypy-lang.blogspot.com/2022/11/mypy-0990-released.html). Pyright even had support for recursive types earlier (https://github.com/microsoft/pyright/issues/569), so there is probably no reason not to model these types correctly.

This PR models these types properly now. Since this has turned a few implicit `Any` into fully typed variables that are not narrowed cleanly, a small number of type ignores were necessary.

Note that regarding the `Argument` it is desirable to model it in a covariant way (i.e. using `Sequence` and `Mapping`) instead of making it invariant unnecessarily (using `List` and `Dict`). If it were modeled invariant, it would for instance mean that a `List[Node]` would not type check as `Argument`, because invariance would mean that it really has to be a `List[Argument]` (i.e., including all the branches of the union type). Since even the name of the type "argument" strongly suggest that it is semantically used as "argument", having covariance natural anyway.

There are no chances in this PR that affect runtime behavior.

12e95aa4ee [BE]: Apply PERF401 autofixes from ruff (#140980)
* Automatically applies ruff rule 401. Turns loops into equivalent list comprehensions which are faster and do not leak the scope of the loop variables.
* list comprehensions not only often have better typing, but are 50+% faster than for loops on overhead. They also preserve length information etc and are better for the interpreter to optimize.
* Manually went back and made mypy happy after the change.
* Also fixed style lints in files covered by flake8 but not by pyfmt

d95aedf5fd [BE] typing for decorators - fx/_compatibility (part 1) (#134202)
Part of #134054.

This corresponds to the pytorch mypy changes from D61493706. Updating takes so
long and touches so many files that it's impossible to land as a whole without conflicting with some other intermediate change.
So landing these 'type: ignore' for pytorch in advance of them actually being needed.

- [Typing] Fix PEP 484 Violation (#105022)
- Update mypy to 1.4.1 (#91983)

That were reverted due to the conflict with internal source repo.

Mostly fixes for PEP-484 violation (i.e. when default arg is set to None, but type is not annotated as optional)
Plus few real fixes:
  - Add missing `_get_upgraders_entry_map` to `torch/_C/__init__.pyi`
  - Add missing return statement to `torch._export. deserialize_graph`
  - Fix error message in `torch.ao.ns.fx.weight_utils.get_lstm_mod_weights`
  - Add assert it `torch/optim/optimizer.py` that Optional list is not None
TODO (in followup PR):
  - Fix erroneous `isinstance` check in `torch/ao/quantization/_pt2e/qat_utils.py`

Unrelated, to bypass CI failures due to the gcc9 dependency update in Ubuntu-18.04:
- Add hack to squash older libstdc++ from conda environment in favor one from OS to `.ci/docker/install_conda.sh`
- Update bazel cuda builds to focal, as with libstdc++-6.0.32 bazel builds loose the ability to catch exceptions (probably because they link with cupti statically, but I could not found where it is done)

424c930f76 Add quantization lowering for nn.PixelShuffle and nn.PixelUnshuffle (#101926)
Similar to https://github.com/pytorch/pytorch/pull/96160 but for the modules
nn.PixelShuffle and nn.PixelUnshuffle.

torch.nn.PixelUnshuffle accepts both float and quantized inputs.
However, previously we would unnecessarily dequantize quantized inputs into floats
before passing them to the function. This commit fixes this by lowering the pattern
[dequant - PixelShuffle - quant].
[dequant - PixelUnshuffle - quant].

Test Plan:

python test/test_quantization.py TestQuantizeFxOps.test_pixel_shuffle_module
python test/test_quantization.py TestQuantizeFxOps.test_pixel_unshuffle_module

e61b842001 [Quant][FX] lower functional conv_transpose ops (#97126)
**Summary**
Support quantizing and lowering functional `conv_transpose1d`, `conv_transpose2d` and `conv_transpose3d`.
Please note that
- `conv_tranpose + relu` fusion is not supported. Remember to keep `relu` node in graph when lowering.
- `conv_tranpose` requires `per-tensor` scheme for weight. Use default `qconfig_mappings` instead of deprecated `qconfig_dict` for test cases.

**Test plan**
python test/test_quantization.py -k test_conv_transpose_not_reference
python test/test_quantization.py -k test_conv_transpose_reference
python test/test_quantization.py -k test_conv_transpose_relu_not_reference
python test/test_quantization.py -k test_conv_transpose_relu_reference
