Updates `_export.aot_compile` to pass a torch IR graph to inductor, allowing inductor to now run the pre_grad_passes, and reuse more of inductor's code.
Also updates the API to only return the `so_path`, and not returning the exported program. The pytree call spec is now serialized and placed inside of the generated model code. When calling the model, because there is no c++ pytree implementation linked yet, we can access the call specs through `get_call_spec()`, and call pytree flatten/unflattenin python.

The default size based auto wrap policy may not be representative of actual usage of the models. We add support for a few handpicked models, and fallback to the size based policy.

As in the title.
The figures below illustrate the performance differences of bsr_dense_mm with optimized parameters and bsr_dense_mm with default parameters (GPU: NVIDIA A100-SXM4-80GB). The first figure represents the performance equilibrium point in BSR tensor sparsity at which value bsr_dense_mm have the same performance characteristics as torch.matmul. The second figure represents speedups from using optimized meta parameters in bsr_dense_mm at its performance equilibrium points with respect to bsr_dense_mm with default meta parameters.
In sum, this PR speeds up `bsr_dense_mm` about 50 % depending on the bsr tensor shape and blocksize and lowers the performance equilibrium points of BSR tensor sparsity and strided tensor for matmul operations.

This PR introduces `scatter_mm` operation (compute `mm` of arbitrary pairs of tensors given in batches of tensors) that is used to implement `bsr_scatter_mm` that is equivalent to `bsr_dense_mm` (the `mm` operation on bsr and strided tensors). The implementation is provided both in Triton (when tensor dimensions are multiples of 16) and in PyTorch (otherwise).
The figures below illustrate the performance differences of `bsr_scatter_mm` and `bsr_dense_mm` (GPU: `NVIDIA GeForce RTX 2060 SUPER`). The first figure represents the performance equilibrium point in BSR tensor sparsity at which value `bsr_scatter_mm` or `bsr_dense_mm` have the same performance characteristics as `torch.matmul`. The second figure represents speedups from using `bsr_scatter_mm` at its performance equilibrium points with respect to `bsr_dense_mm`.

In sum:
- `bsr_scatter_mm` is about 2x faster than `bsr_dense_mm` for small block sizes of 16 and 32 and large tensors [GPU: `NVIDIA GeForce RTX 2060 SUPER`].
- `bsr_scatter_mm` is up to 2x faster than `bsr_dense_mm` for small block sizes of 16 and large tensors [GPU: `NVIDIA A100-SXM4-80GB`].
- `bsr_dense_mm` is up to 20 % faster than `bsr_scatter_mm` for block sizes of 64 or larger [GPU: `NVIDIA GeForce RTX 2060 SUPER`].
- However, `bsr_dense_mm` fails with `OutOfResources` exception for block sizes of 256 or larger whereas `bsr_scatter_mm` succeeds.

Did some easy fixes from enabling TRY200. Most of these seem like oversights instead of intentional. The proper way to silence intentional errors is with `from None` to note that you thought about whether it should contain the cause and decided against it.

Fixes#109604
Resubmit gh-109715 + several skips and small fixes to make tests pass.
The main fix here is by @ysiraichi : previously, dynamo did not resume tracing numpy ndarrays after a graph break.
While at it, fix several small issues Yukio's fix uncovers:
- graph break gracefully on numpy dtypes which do not map to torch.dtypes (uint16 etc)
- recognize array scalars in dynamo, treat them as 0D ndarrays
- make sure that iterating over torch.ndarray generates arrays not bare tensors

Summary:
Currently we have shape constraints in semi-structured sparsity for both
CUTLASS and cuSPARSELt
These shape constraints unfortunately apply to both the dense and sparse
matrices in sparsedense matmul.
This PR adds in support for calling `F.pad` in order to pad dense
matrices to the right size with zeros and then pull out the
corresponding rows from the resultant result matrix.
We also throw a warning in this case.
The tests have also been updated to take in a dense_input_shape
parameter.

This PR addresses the persistent issue of merge conflicts in the benchmarks/dynamo/ci_expected_accuracy/ directory, specifically those arising from frequently updated CSV files. Based on @malfet suggestion, the solution implemented adds three spaces between each line in the CSV files. This approach has proven effective in preventing merge conflicts, as evidenced in [D50239634](https://www.internalfb.com/intern/diff/D50239634/). Regardless of these changes the extra new lines should still allow the csvs to be ingested as normal.
If you have access to the diff:
Normally, modifying a line that is later altered in the stack results in a merge conflict during restacking. With this new spacing strategy, lines that are not modified further down the stack will not trigger merge conflicts, achieving our intended outcome.

Fix https://github.com/pytorch/pytorch/issues/109736 .
HF pin move causes regression on accuracy check for HF models on the dashboard. Manually reverting the HF PR ( https://github.com/huggingface/transformers/pull/24696/files ) could recover, but this may hide some real issue. I happen to found that using a warm matmul max-autotune cache can work around the issue. Or putting it in another way:
- make all calls to check_cache cache miss repro the issue
- make all cals to check_cache cache hit works around the issue
I did some sort of 'bisect' to force halving the amount of cache miss each time while still make sure we can repro. Luckily reducing to a single cache miss still repro the issue. With more debugging, it turns out that it's the call to `torch.randn` on cuda device causing the problem.
The fix is to make sure we restore the rng state when we generate random inputs for max-autotune benchmarking.
TBH, I can not fully explain the root cause although I know it's caused by rng state change. AOTAutograd already has some logic to preserve rng state. And I can not repro the issue in unit tests. I have a few guess why the RNG state is not restored in the first place after we generate random inputs for max-autotune:
- maybe AOTAutograd misses some corner case to preserve the rng state
- maybe for the failed models, there are some eager fallback that's not handled by inductor. And if those fallback calles random number related APIs, we will see the issue. But again I don't find a good way to simulate this.
Repro:
```
TORCHINDUCTOR_BENCHMARK_KERNEL=1 TORCHINDUCTOR_MAX_AUTOTUNE_GEMM=1 CUDA_VISIBLE_DEVICES=3 time python benchmarks/dynamo/huggingface.py --backend inductor --amp --accuracy --only PLBartForCausalLM --training --cold-start-latency
```
We always repro the issue without the PR but pass the accuracy check with the PR.

Summary:
Change AOTInductor to directly return output tensors instead of taking pre-allocated output tensors to return the results. This gives several benefits:
* It makes sure AOTInductor has the same behavior when managing the output tensors as the default Inductor, which is widely tested and thus more reliable.
* As we have debugged before, there are cases we still have to codegen extra copy_ ops to fill the pre-allocated output tensors which doesn't make sense for performance.
* With the coming enhanced memory planning, this again will make sure the memory planning logic is the between AOTInductor and Inductor, which will greatly simplify the problem and improve the reliability.
This change also combines D49494954 from Yang and https://github.com/pytorch/pytorch/pull/109560 from Angela.

`python benchmarks/dynamo/torchbench.py --multiprocess` currently fails due to initializing distributed multiple times:
```
torch.distributed.DistNetworkError: The server socket has failed to listen on any local network address. The server socket has failed to bind to [::]:6789 (errno: 98 - Address already in use). The server socket has failed to bind to 0.0.0.0:6789
(errno: 98 - Address already in use).
```
Because torchbench calls itself via mp.spawn, there is the parent run (with `--multiprocess`) and child runs (with `--multiprocess --only <model>`).
This PR addresses this by fixing two issues:
1) distributed is initialized once in parent run and once in child runs, it should be initialized only in child runs where we have accurate rank and world size info
2) torchbench overrides CUDA_VISIBLE_DEVICES/world_size sometimes, but it shouldn't for distributed use cases where we want to use all available gpus
I am also adding a CI test to cover this type of issue in #109311

Previously, the code for passing inputs to exported program was:
```
if kwargs:
return (args, kwargs)
else:
return args
```
However, this causes some inconsistency where if the original input contains args and kwargs, the treespec would be a tuple containing a tuple of arguments, and a dictionary of keyword arguments. But if the original input only contained args, the treespec would just be a tuple of arguments. This inconsistency causes some inconveniences in the runtime.
So I updated the code to just always keep the kwargs around.

Enables two ruff rules derived from pylint:
* PLR1722 replaces any exit() calls with sys.exit(). exit() is only designed to be used in repl contexts as may not always be imported by default. This always use the version in the sys module which is better
* PLW3301 replaces nested min / max calls with simplified versions (ie. `min(a, min(b, c))` => `min(a, b. c)`). The new version is more idiomatic and more efficient.
