Add similar semantics for creating a buffer object similar to creating a parameter. This is done by introducing a new `Buffer` class that can be used for type disambiguation. The underlying functionality of registering a buffer remains the same as the `register_buffer` method has not been changed. The `persistent` parameter in the `Buffer` type is to indicate whether a buffer object should be persistent or not. Other non-test changes have to do with getting the new `Buffer` type recognized by inductor and dynamo. Remaining changes are test changes to make sure that the `Buffer` type can be used as a drop in replacement for `register_buffer` as it just leads to `register_buffer` being called. The addition of this new functionality still allows for normal tensors to be used as buffers so these changes are intended to be backwards compatible.

This commit improves the export of aten::slice() to ONNX in the following ways:
1. The step size can be an input tensor rather than a constant.
2. Fixes a bug where using a 1-D, 1-element torch tensor as an index created a broken ONNX model.
This commit also adds tests for the new functionality.

- In #102759, the support for `quantized::conv_transposeNd` was introduced. This incorrectly set `output_padding` to all zeros. Turns out, you can specify output_padding in PyTorch, but this parameter was not being unpacked correctly and thus did not show up in the python torch->onnx code.
- This adds unpacking of output_padding in `unpack_quantized_weights.cpp` when needed. It also adds this as a parameter in the python functions and uses that (and removes the all-zero defaults)
- Another issue with #102759 is that it only added these new ops to opset10 without adding the ability to specify axis in opset13. This PR also fixes this.

- Extend support:
- quantized::conv1d
- quantized::conv3d
- quantized::conv3d_relu
- quantized::conv_transpose1d
- quantized::conv_transpose2d
- quantized::conv_transpose3d
- Note: quantized::{conv1d_relu,conv2d,conv2d_relu} already supported.
- To support this, quantization unpacking added for:
- conv1d
- conv_transpose1d
- conv_transpose2d
- conv_transpose3d
- Note: conv3d/conv3d_relu already had weights unpacking set up, even though it didn't have torch.onnx support.
- Add tests.
- The 3D tests will fail if run with the qnnpack backend (e.g., on Apple silicon Mac), so added decorator skipIfQuantizationBackendQNNPack.
- Minor fix in `aten/src/ATen/native/quantized/cpu/qconv.cpp` for 3D convolutions (triggered by added tests).

Fixes#92576 , checking the following as described in the documentation:
"source.shape[dim] == len(index) and source.shape[i] == self.shape[i] for i != dim"
Would be happy to iterate on this if there are any issues, and would be happy to implement the checking for the CUDA and MPS implementations of index_add_.

As for unit tests - in this PR I only fixed LSTM unit test to properly use dynamic axes and expose export issue by running test with same ONNX for additional inputs.
If the changes approved, we should also fix the rest of the tests (RNN/GRU and beyond).
I have verified the following updated tests are working with new code and failing with the old code:

__What?__
Per discussion at #94634, deprecate `masked_fill` with non-bool masks. Deprecation warnings were previously added by #22261, but not for Apple MPS. I can revert the MPS changes if deprecation warnings are wanted first tho. See also #96112.
Fixes#85063 and #89320.
__Further Development?__
- Fixed the mask dtype checking for the cuda dispatch for `masked_fill` in `aten/src/ATen/native/cuda/Indexing.cu`

This PR addresses issue [#81075](https://github.com/pytorch/pytorch/issues/81075), making `torch.stft` compatible with ONNX Opset 17's STFT operator.
The conversion works for _most_ of `torch.stft` functionality:
- Batched or unbatched inputs
- Normalization
- Pre-computed windows
- Rectangular windows
- One-sided returns
- Window centering (implicitly supported)
What is currently _not_ supported is **complex types**, due to the lack of conversion functionality between PyTorch and ONNX (https://github.com/pytorch/pytorch/issues/86746).
Regardless, this is easy to bypass by setting `return_complex=False` when using `torch.stft`.
Note that there is already a draft PR to address this (https://github.com/pytorch/pytorch/pull/83944), but it is currently closed and it only partially addresses the conversion (i.e., most of `torch.stft` functionality is lacking, and unit tests are missing).

This commit fixes a bug where the ONNX exporter for circular padding queried the input tensor shape in order to get the correct 'end' index for a slice node. This doesn't work when the axis in question is has dynamic size. The commit fixes this by setting the 'end' index to INT_MAX, which is the recommended way of slicing to the end of a dimension with unknown size per ONNX spec.
See https://onnx.ai/onnx/operators/onnx__Slice.html
Also adds a regression test.

All this time, PyTorch and ONNX has different strategy for None in output. And in internal test, we flatten the torch outputs to see if the rest of them matched. However, this doesn't work anymore in scripting after Optional node is introduced, since some of None would be kept.
#83184 forces script module to keep all Nones from Pytorch, but in ONNX, the model only keeps the ones generated with Optional node, and deletes those meaningless None.
This PR uses Optional node to keep those meaningless None in output as well, so when it comes to script module result comparison, Pytorch and ONNX should have the same amount of Nones.

Optimize unnecessary collection cast calls, unnecessary calls to list, tuple, and dict, and simplify calls to the sorted builtin. This should strictly improve speed and improve readability.

From PR: https://github.com/pytorch/pytorch/pull/58691, Replacing the second input of `Gather` 0 to 1 affects other innocent Nodes. In Issue #91526 onnx::range starts from 0, the 0 is changed by this mechanism, as it's shared with onnx::Gather. This PR intends to create a whole independent Constant 0 for replacement. NOTE: The PR passes all existing RNN tests locally in case CI doesn't include RNN test.

#84624 introduces an update on `torch.norm` [dispatch logic](eaa43d9f25/torch/functional.py (L1489)) which now depends on `layout`. Resulting in regressions to export related operators from TorchScript.
This PR resolves the regression by partially supporting a subset use case of `prim::layout` (only `torch.strided`), `aten::__contains__` (only constants) operators. It requires much more effort to properly support other layouts, e.g. `torch.sparse_coo`. Extending JIT types, and supporting related family of ops like `aten::to_sparse`. This is out of the scope of this PR.

Fixes https://github.com/pytorch/pytorch/issues/84365 and more
This PR addresses not only the issue above, but the entire family of issues related to `torch._C.Value.type()` parsing when `scalarType()` or `dtype()` is not available.
This issue exists before `JitScalarType` was introduced, but the new implementation refactored the bug in because the new api `from_name` and `from_dtype` requires parsing `torch._C.Value.type()` to get proper inputs, which is exactly the root cause for this family of bugs.
Therefore `from_name` and `from_dtype` must be called when the implementor knows the `name` and `dtype` without parsing a `torch._C.Value`. To handle the corner cases hidden within `torch._C.Value`, a new `from_value` API was introduced and it should be used in favor of the former ones for most cases. The new API is safer and doesn't require type parsing from user, triggering JIT asserts in the core of pytorch.
Although CI is passing for all tests, please review carefully all symbolics/helpers refactoring to make sure the meaning/intetion of the old call are not changed in the new call
