Changes by apply order:
1. Replace all `".."` and `os.pardir` usage with `os.path.dirname(...)`.
2. Replace nested `os.path.dirname(os.path.dirname(...))` call with `str(Path(...).parent.parent)`.
3. Reorder `.absolute()` ~/ `.resolve()`~ and `.parent`: always resolve the path first.
`.parent{...}.absolute()` -> `.absolute().parent{...}`
4. Replace chained `.parent x N` with `.parents[${N - 1}]`: the code is easier to read (see 5.)
`.parent.parent.parent.parent` -> `.parents[3]`
5. ~Replace `.parents[${N - 1}]` with `.parents[${N} - 1]`: the code is easier to read and does not introduce any runtime overhead.~
~`.parents[3]` -> `.parents[4 - 1]`~
6. ~Replace `.parents[2 - 1]` with `.parent.parent`: because the code is shorter and easier to read.~

The `usort` config in `pyproject.toml` has no effect due to a typo. Fixing the typo make `usort` do more and generate the changes in the PR. Except `pyproject.toml`, all changes are generated by `lintrunner -a --take UFMT --all-files`.

Something people found confusing was that whether or not a native::
signature would get SymInt or not in its type was based on the dispatch
key. This changes it so that SymInt or not in type is based on whether
or not you have _symint in the name of the kernel or not. This means
that even when we make operators support SymInt, you no longer have to
go and update all the preexisting definitions; instead, you now
selectively write _symint to opt individual kernels into SymInt support.
I then go and update a bunch of kernels that don't have proper SymInt
support to make use of this convention. There is some hacking around
for view generation code.
I also add support for external backends to specify 'symint' operators, for which we generate SymInt signatures instead of regular signatures.

This is to get a conversation started.
* @JackCaoG we could add attributes to items in `ir_codegen` section to customize IR generation logic (e.g. not generating `::Lower`). Though it could be a bit tricky to thread it through.
* Adding an extra argument to `map_codegen` to filter native functions out seems like a step in the right direction. Otherwise, it's a bit confusing how do we go from a full list to a codegen list.

With ufmt in place https://github.com/pytorch/pytorch/pull/81157, we can now use it to gradually format all files. I'm breaking this down into multiple smaller batches to avoid too many merge conflicts later on.
This batch (as copied from the current BLACK linter config):
* `tools/**/*.py`
Upcoming batchs:
* `torchgen/**/*.py`
* `torch/package/**/*.py`
* `torch/onnx/**/*.py`
* `torch/_refs/**/*.py`
* `torch/_prims/**/*.py`
* `torch/_meta_registrations.py`
* `torch/_decomp/**/*.py`
* `test/onnx/**/*.py`
Once they are all formatted, BLACK linter will be removed.

Add codegen infrastructure to generate IR nodes for non-native ops.
The proposed change is to add a `non_native` key to the `{backend}_native_functions.yaml` file that contains schema definitions similar to what is found in `native_functions.yaml`. e.g.
```
non_native:
...
- func: expand(Tensor input, int[] size, bool is_scalar_expand) -> Tensor
...
```
these definitions are parsed into a `LazyIrSchema` that can be used for generating IR nodes using `GenLazyIR`.
Fixes#74628
