Summary:
Match updated `Embedding` docs from https://github.com/pytorch/pytorch/pull/54026 as closely as possible. Additionally, update the C++ side `Embedding` docs, since those were missed in the previous PR.
There are 6 (!) places for docs:
1. Python module form in `sparse.py` - includes an additional line about newly constructed `Embedding`s / `EmbeddingBag`s
2. Python `from_pretrained()` in `sparse.py` (refers back to module docs)
3. Python functional form in `functional.py`
4. C++ module options - includes an additional line about newly constructed `Embedding`s / `EmbeddingBag`s
5. C++ `from_pretrained()` options
6. C++ functional options

Summary:
As this diff shows, currently there are a couple hundred instances of raw `noqa` in the codebase, which just ignore all errors on a given line. That isn't great, so this PR changes all existing instances of that antipattern to qualify the `noqa` with respect to a specific error code, and adds a lint to prevent more of this from happening in the future.
Interestingly, some of the examples the `noqa` lint catches are genuine attempts to qualify the `noqa` with a specific error code, such as these two:
```
test/jit/test_misc.py:27: print(f"{hello + ' ' + test}, I'm a {test}") # noqa E999
test/jit/test_misc.py:28: print(f"format blank") # noqa F541
```
However, those are still wrong because they are [missing a colon](https://flake8.pycqa.org/en/3.9.1/user/violations.html#in-line-ignoring-errors), which actually causes the error code to be completely ignored:
- If you change them to anything else, the warnings will still be suppressed.
- If you add the necessary colons then it is revealed that `E261` was also being suppressed, unintentionally:
```
test/jit/test_misc.py:27:57: E261 at least two spaces before inline comment
test/jit/test_misc.py:28:35: E261 at least two spaces before inline comment
```
I did try using [flake8-noqa](https://pypi.org/project/flake8-noqa/) instead of a custom `git grep` lint, but it didn't seem to work. This PR is definitely missing some of the functionality that flake8-noqa is supposed to provide, though, so if someone can figure out how to use it, we should do that instead.

Summary:
This PR adds a `padding_idx` parameter to `nn.EmbeddingBag` and `nn.functional.embedding_bag`. As with `nn.Embedding`'s `padding_idx` argument, if an embedding's index is equal to `padding_idx` it is ignored, so it is not included in the reduction.
This PR does not add support for `padding_idx` for quantized or ONNX `EmbeddingBag` for opset10/11 (opset9 is supported). In these cases, an error is thrown if `padding_idx` is provided.

First part of #3867 (Pooling operators still to do)
This adds a `padding='same'` mode to the interface of `conv{n}d`and `nn.Conv{n}d`. This should match the behaviour of `tensorflow`. I couldn't find it explicitly documented but through experimentation I found `tensorflow` returns the shape `ceil(len/stride)` and always adds any extra asymmetric padding onto the right side of the input.
Since the `native_functions.yaml` schema doesn't seem to support strings or enums, I've moved the function interface into python and it now dispatches between the numerically padded `conv{n}d` and the `_conv{n}d_same` variant. Underscores because I couldn't see any way to avoid exporting a function into the `torch` namespace.
A note on asymmetric padding. The total padding required can be odd if both the kernel-length is even and the dilation is odd. mkldnn has native support for asymmetric padding, so there is no overhead there, but for other backends I resort to padding the input tensor by 1 on the right hand side to make the remaining padding symmetrical. In these cases, I use `TORCH_WARN_ONCE` to notify the user of the performance implications.

- Explain that SiLU is also known as swish and that it stands for "Sigmoid Linear Unit."
- Ensure that "SiLU" is correctly capitalized.
I believe these changes will help users find the function they're looking for by adding relevant keywords to the docs.

Summary:
Fixes https://github.com/pytorch/pytorch/issues/52257
## Background
Reverts MHA behavior for `bias` flag to that of v1.5: flag enables or disables both in and out projection biases.
Updates type annotations for both in and out projections biases from `Tensor` to `Optional[Tensor]` for `torch.jit.script` usage.
Note: With this change, `_LinearWithBias` defined in `torch/nn/modules/linear.py` is no longer utilized. Completely removing it would require updates to quantization logic in the following files:
```
test/quantization/test_quantized_module.py
torch/nn/quantizable/modules/activation.py
torch/nn/quantized/dynamic/modules/linear.py
torch/nn/quantized/modules/linear.py
torch/quantization/quantization_mappings.py
```
This PR takes a conservative initial approach and leaves these files unchanged.
**Is it safe to fully remove `_LinearWithBias`?**
Pull Request resolved: https://github.com/pytorch/pytorch/pull/52537
Test Plan:
```
python test/test_nn.py TestNN.test_multihead_attn_no_bias
```
## BC-Breaking Note
In v1.6, the behavior of `MultiheadAttention`'s `bias` flag was incorrectly changed to affect only the in projection layer. That is, setting `bias=False` would fail to disable the bias for the out projection layer. This regression has been fixed, and the `bias` flag now correctly applies to both the in and out projection layers.

This PR pulls `__torch_function__` checking entirely into C++, and adds a special `object_has_torch_function` method for ops which only have one arg as this lets us skip tuple construction and unpacking. We can now also do away with the Python side fast bailout for `Tensor` (e.g. `if any(type(t) is not Tensor for t in tensors) and has_torch_function(tensors)`) because they're actually slower than checking with the Python C API.

It's in general helpful to support int32 indices and offsets, especially when such tensors are large and need to be transferred to accelerator backends. Since it may not be very useful to support the combination of int32 indices and int64 offsets, here we enforce that these two must have the same type.

I added bicubic grid sampler in both cpu and cuda side, but haven't in AVX2
There is a [colab notebook](https://colab.research.google.com/drive/1mIh6TLLj5WWM_NcmKDRvY5Gltbb781oU?usp=sharing) show some test results. The notebook use bilinear for test, since I could only use distributed version of pytorch in it. You could just download it and modify the `mode_torch=bicubic` to show the results.
There are some duplicate code about getting and setting values, since the helper function used in bilinear at first clip the coordinate beyond boundary, and then get or set the value. However, in bicubic, there are more points should be consider. I could refactor that part after making sure the overall calculation are correct.
