Summary:
Add a customizable loss function callback to NodeAccuracySummary to
allow users to pass in their own loss function.
Also, fix some type errors and propagate better exception messages when
unexpected tensor comparisons occur. Finally, enhance the robustness of
`generate_numeric_debug_handle` in the case where it is called multiple
times on the same model, by avoiding reuse of the same IDs.
Test Plan: Added a test for this case in `test_numeric_debugger`.

PR changes how `reconstruct` is done for a ConstDict. As of today, it works as follow:
(1) codegen(...) each pair of key/value
(2) create a new dictionary to hold the new items
(3) clear the original dictionary
(4) update the original dict with the one created in (2)
We do a micro optimization in the generated bytecode to:
- Only codegen the items that changed.
- Only clear the original dictionary if a key was removed.

1. We want to take option 3 as discussed in https://github.com/pytorch/pytorch/issues/135712, so every time when we retry, we create a new TCPStore server first so that we don't need to append attempt count as prefix and avoid eventually TCPStore sync failure. (This is only for the TCPStore sharing enabled case)
2. We start a new server bound to an ephemeral port (i.e. 0) so it gets assigned to a free port. We then pass that downstream (trainer or c10d). By doing so, TCPStore is managed by the elastic agent rather than having a race condition on binding to a specific port in the trainer.
3. Then the port be broadcasted for dynamic_rendezvous.
Only one more question, what do we do about the store created from (_create_tcp_store) torch/distributed/elastic/rendezvous/c10d_rendezvous_backend.py, are we ok with creating a duplicate TCPStore server?

Fixes#93843
`EmbeddingBag()` / `embedding_bag()` support 1D inputs with offsets to handle raggedness. NJT is a natural fit here as it already maintains offsets of the same form. This PR updates the python-side to support NJT and adds corresponding OpInfo-based NJT tests.

Summary:
After the previous refactor, we can now call load_with_key directly from AOTAutogradCache to use the remote FXGraphCache.
This does *not* implement a remote AOTAutogradCache. It just allows AOTAutogradCache to work with remote FXGraphCache.

- Sometimes having access to the `MixedPrecisionPolicy` in the `fsdp_pre_all_gather` is useful. See [here](https://github.com/pytorch/ao/pull/748/files#r1760375325) in the torchao INT8 mixed precision training PR.
- Sometimes having access to the owning `nn.Module` allows for using it for saving state. See [here](https://github.com/pytorch/pytorch/issues/114299#issuecomment-2298692762) for an example.
The major paint point here is how to deal with backward compatibility. For now, we use `signature.inspect` to check if the user subclass follows the old vs. new signature. However, for the new signature, the `param_dtype` in the post-all-gather is redundant, as if the user needed it, the user could save it from the `mp_policy` passed in the pre-all-gather now.

By refactoring this way, I can put a non-expiring LRU cache here.
Splitting also will make it easier for me to tell who is using up all
the time.

Fix circular import in `torch/distributed/utils.py` found when running internal test, see D62901023. Curious why this wasn't causing any issue. Is this relevant code deprecated and no longer used?

Fixes#131337
- add `arg_type` for workspace_arg, the type is consistent with the type in `generate_workspace_allocation()`.
- do not generate example tensors for `workspace`, and use `generate_workspace_allocation()` instead.
- add workspace allocation generation code to `kernel_autotune_calls`. e.g.
```python
workspace = empty_strided_cuda((1280, ), (1, ), torch.uint8)
workspace.zero_()
.....
triton_spl_fused_add_cumprod_0.run(buf2, arg0_1, arg1_1, workspace, 1, 10000, grid=split_scan_grid(1, 10000), stream=stream0)
del buf2, arg0_1, arg1_1, workspace
```
- add `empty_strided_cuda = torch._C._dynamo.guards._empty_strided_cuda` to the header of triton autotune code.
The generated cpp has lines like below, so we also implement a `zero_()` for ` AtenTensorHandle `.
```cpp
static constexpr int64_t int_array_0[] = {1280L, };
static constexpr int64_t int_array_1[] = {1L, };
AtenTensorHandle workspace_handle;
AOTI_TORCH_ERROR_CODE_CHECK(aoti_torch_empty_strided(1, int_array_0, int_array_1, cached_torch_dtype_uint8, cached_torch_device_type_cuda, 0, &workspace_handle));
RAIIAtenTensorHandle workspace(workspace_handle);
workspace.zero_();
```
- Fix handle grid_fn for grid computation. Pass in "RBLOCK" to `split_scan_grid`
- Fix dynamic shapes:
Without the fix we generate code that looks like this `workspace = empty_strided_cuda((32*((255 + s0) // 256), ), (1, ), torch.uint8)` when doing triton autotune and `s0` is not defined.
The solution approach is to use `V.graph.sizevars.size_hint(nbytes)` to realize the workspace size for triton autotune. Note that we only realize it for triton autotune code, but not for the cpp cuda code.
- We also generate slightly different cpp code depending on if `abi_compatible` is turned on.
```cpp
RAIIAtenTensorHandle workspace(workspace_handle);
AOTI_TORCH_ERROR_CODE_CHECK(aoti_torch_zero_(workspace.get()));
```
vs
```cpp
at::Tensor workspace = at::detail::empty_strided_cuda({8L*(c10::div_floor_integer(static_cast<int64_t>((255L + s0)), static_cast<int64_t>(256L))), }, {1L, }, at::kByte, c10::DeviceType::CUDA);
workspace.zero_();
```

**Motivations**:
A topological order of the scheduler nodes that optimize the liveness of buffers can reduce the peak memory utilization. This has been observed and studied e.g., [here](https://arxiv.org/pdf/1910.02653) and [here](https://proceedings.mlr.press/v202/steiner23a/steiner23a.pdf).
**Solutions**:
1. implement a peak memory estimator via liveness analysis
2. implement a few memory aware topological sorting algorithms and pick the one with the lowest peak memory
**Results**:
On some models we can reduce the peak memory significantly:
| model | batch size | peak_memory baseline | peak_memory new | ratio |
|:-----------------------------:|:----------:|:--------------------:|:---------------:|:-----:|
| alexnet | 128 | 1.17 | 0.99 | 1.19 |
| vgg16 | 64 | 4.10 | 3.57 | 1.15 |
| DebertaV2ForQuestionAnswering | 1 | 11.60 | 10.56 | 1.10 |
In the presence of compiler based AC, peak memory can be further reduced:
| model | batch size | peak_memory baseline | peak_memory new | ratio |
|:------------------------------:|:----------:|:--------------------:|:---------------:|:-----:|
| AlbertForMaskedLM | 4 | 6.87 | 6.43 | 1.07 |
| AlbertForQuestionAnswering | 4 | 8.69 | 7.76 | 1.12 |
| MobileBertForQuestionAnswering | 128 | 4.67 | 3.90 | 1.20 |

**Other infos:**
* neutral model runtime, because the the reordering happens after fusion. So memory saving is _for free_.
* minimal compile time overhead as the algorithm is linear in the number of edges of the inductor graph. For all hugglingface benchmark models, the additional compile time is less than 1 second.
* no peak memory regression since we only adopt a new order if the peak memory is reduced based on the estimator. However, the model is unaware of operators' working memories, but for large models, the working memory should be negligible. We haven't observed any significant regressions on all of our tests.

Fixes#134848
For BF16/FP16, when a tensor is specified in `out` parameter of mean, the mean kernel should use its storage for output, but that doesn't happen, since an `at::to` in the current code causes storage to be allocated again, but the `out` parameter tensor's storage doesn't get updated, resulting in it not holding the mean output.

Avoid allocating memory or dry-running the submodule during stage init.
Save user-provided input/output metadata during stage init, to allow
lazily initializing the buffers before the first step call.
Later, we plan to build on top of this to add lazy shape inference
(#130856) so that no input/output shapes are required at stage init.
For now, we require input/output tensors for stage init, but these
should be on meta device and stage should not allocate any real memory.
Note: this needs more thorough testing and review, but it worked on the
torchtitan 3d test.
TODO:
- delete 'device' arg from PipelineStage ctor? (move it to inferred from
args tensors passed to first step call? separate PR.
- delete 'output_args' from PipelineStage ctor? we don't actually need
it, but we use it to do shape validation, which is why I didn't remove
it in this PR. Proposal: leave it until we add lazy shape inference?
