Fixes #ISSUE_NUMBER
## Background
Task: [T222738229](https://www.internalfb.com/intern/tasks/?t=222738229)
It's the first starter task on the project **_Enabling TorchNative Standalone on Whisper_**. We are using cshim to create a layer of abstraction between _**libtorch**_ and **_AOTInductor generated artifacts_**.
So we needed to add an entry in the cshim for every API surface in libtorch. And we only care about operators that AOTInductor does not handle. And for this task, we only wanted to add it for the following ops.
## What I've done?
4 new fallback ops are added that show up in the Whisper model. (torchgen/aoti/fallback_ops.py)
- aten.permute (default)
- aten.squueze (dim)
- aten.abs (default)
- aten.hann_window (default)
Then I ran the below command to generate new header C shim header files. As it says [here](7e86a7c015/torchgen/gen.py (L2424-L2436%20for%20details))
`python torchgen/gen.py --update-aoti-c-shim`
Then, `python setup.py develop` to rebuild PyTorch
## Testing
Also 4 new tests have been added on test/inductor/test_aot_inductor.py
- test_proxy_executor_permute
- test_proxy_executor_abs
- test_proxy_executor_squeeze
- test_proxy_executor_hann
I ran these commands to test it (inside local pytorch root folder):
`python test/inductor/test_aot_inductor.py -k test_proxy_executor_permute`
`python test/inductor/test_aot_inductor.py -k test_proxy_executor_abs`
`python test/inductor/test_aot_inductor.py -k test_proxy_executor_squeeze`
`python test/inductor/test_aot_inductor.py -k test_proxy_executor_hann`
## NOTE:
I didn't see any order between the tests inside _test/inductor/test_aot_inductor.py_. That's why, I added new tests just after the test given in the example.
