`torch.overrides.get_testing_overrides` does not function as intended for native tensor methods/operations
Labels: triaged, module: __torch_function__

### 🐛 Describe the bug

`torch.overrides.get_testing_overrides` (introduced in #33791) does not appear function as intended for native tensor methods/operations. For example, the following code can be used to discern the signature of `torch.Tensor.size`, as simply using `inspect.signature(torch.Tensor.size)` will yield an error:

```
import torch
import inspect

d = torch.overrides.get_testing_overrides()
print(inspect.signature(d[torch.Tensor.size])
```

This returns `size (self)`. As can be seen here: https://pytorch.org/docs/stable/generated/torch.Tensor.size.html, the expected output is `size (self, dim=None)`. Surprisingly, for `torch.Tensor.permute`, `permute (self, dim)` is returned. This is neither consistent with https://pytorch.org/docs/stable/generated/torch.Tensor.permute.html#torch.Tensor.permute or https://pytorch.org/docs/stable/generated/torch.permute.html#torch.permute.

It appears that the dictionary created and used in https://github.com/pytorch/pytorch/blob/master/torch/overrides.py#L1301 is outdated and/or contains incorrect entries.
