Summary: This fix does three things:
1. When we add inputs from partioner to the top level graph module, we insert in the order of partioner which is not guaranteed to be same as original graph inputs. This PR fixes that.
2. When we replace autograd ops with HOP, we create new submodules and access their outputs via getitem calls. As a result, previous node names associated with getitem gets updated, resulting in the graph being different from produced graph signature. So I just update the graph signature accordingly.
3. We run runtime_assertion pass before autograd HOP pass because the constraints won't be populated correctly.

Summary:
By default, some inferred dynamic shapes guards/constraints that are not expressible with the current dynamic shapes language will lead to specialization to the concrete input values provided. If disable_forced_specializations is set to True, we will not specialize, and will not perform runtime checks on such produced guards. Instead, we allow the user to specify arbitrary shapes, and fail during runtime if the inputs are invalid. Constraints expressible with the language (e.g. ranges, linear derived dims) will still be enforced, and behavior for all other guards remains the same.
Cases where we typically specialize are reshapes:
```
x: [4, 6] # [s0, s1]
x = x.reshape([x.shape[0] - 1, -1])
# this emits a guard Mod(s0*s1, s0-1) = 0, we specialize on s0=4, s1=6
x: [4, 6], y: [24] # [s0, s1], [s2]
x = x.reshape([-1]) + y
# this emits a guard s0*s1 = s2, we specialize on s0=4, s1=6, s2=24
```
For now only applicable for non-strict mode (need to figure out how to pass this flag into dynamo's call of produce_guards).
Test Plan: Added test case that checks compilation, runtime, and suggested fixes behavior.

Fixes [internal error](https://fb.workplace.com/groups/1075192433118967/permalink/1416709435633930/).
The issue is that the asserting nodes added in the `insert_deferred_runtime_assertion` pass do not contain metadata that the ExportedProgram requires the graph to have. One solution to fix this is to retrace the entire module, or another solution is to manually add back this metadata.
This diff implements the latter solution (manually add back the metadata) through hooking into fx.graph's `create_node` function, and adding export-specific metadata for every node that is created. The reason I did this is so that the `insert_deferred_runtime_assertion` does not have to know about what metadata export wants.

A re-land of #124239.
This PR fakify ScriptObject inputs and attributes in export non-strict mode by default.
The basic idea is to only fakify the script object during tracing (i.e. aot_export). After we get the traced graph module, eagerly executing, serializing, or running more passes will use the real script objects. This is essentially treating the script object as constant tensor.
Concretely, we
fakify all the script object inputs, and module attributes (gathered by constant_attrs).
patch the module's attributes with fakified script object
right after aot_export, remove the patching (to avoid changing the original module) then modify the exported graph module's attribute to real script object.

Summary:
Fixing the implementation of `_flatten_dynamic_shapes()`, to follow how `_process_dynamic_shapes()` does it. The previous implementation would misinterpret some nested dynamic shapes specs, causing it to miss out on some shapes specs, for example with nested inputs/constant input tuples:
```
inputs = (
(2, 1),
(
torch.randn(2, 1),
torch.randn(2, 2),
torch.randn(2, 3),
)
)
dynamic_shapes = (
(None, None),
(
None,
None,
None,
)
)
```
This would get interpreted as 2 shapes specs for 2d and 3d tensors. Fixing so this doesn't happen.

This PR introduces a new way of building `dynamic_shapes` for export. The idea is to build up a mapping from input tensors to the dynamic shapes that should be assigned to their corresponding fake tensors.
This mapping is automatically converted to the current form of `dynamic_shapes`, which must exactly match the structure of inputs. We do this by using pytree utils.
With the current `dynamic_shapes`, we had to be careful about user-defined classes that are registered with pytree, since such classes are not necessarily polymorphic containers; they may be fine containing tensors, but not dynamic shapes. Thus we had decided to allow input instances of such classes to be associated with dynamic shapes in flattened form. This decision needs to be mirrored in this PR as well. To make it easier to keep these code paths in sync, we refactor the current recursive procedure for associating inputs with dynamic shapes to use the same pytree utils. This needs minor fixes to a few tests where `dynamic_shapes` were not exactly matching the structure of inputs.

Summary:
Fixes https://github.com/pytorch/pytorch/issues/122842
Currently, calling ep.module() on an ExportedProgram leads to a GraphModule with a default forward signature (e.g. arg_0, arg_1, ...). This leads to original placeholder names disappearing for retracing/re-exporting.
Fixing this issue by creating a forward_arg_names field (will take renaming suggestions for this), that stores the positional & keyword arg names that are used. These names aren't present in the call_spec currently stored, and requires a major version bump for the ExportedProgram schema.
Test Plan: Tests exist for export, but names are now changed from generic (e.g. arg_0, arg_1) to follow user inputs (e.g. x, y)

Summary:
There are multiple things implemented incorrectly in non strict for reparametrizing state dict:
1. The same fake tensor should be generated for duplicated weights.
2. We should snapshot state dict in the beginning to always hold the invariant that ep.state_dict == mod.state_dict()
3. We will overwrite real weights with fake weights if we don't restore the weights in LIFO ordering.
4. We don't turn on strict checking which could sliently fail on corner cases.
This diff aims to solve all these issues at once.

The process for populating range_constraints follows separate methods for non-strict (`make_constraints`), and strict (`_process_constraints`). The strict method is somewhat more convoluted, and the analysis that Dynamo performs for strict is already present as part of the non-strict process in make_constraints (produce_guards(), running the export constraint solver).
This PR kills _process_constraints() and replaces calls with make_constraints, without duplicating the work that Dynamo already does.

Summary:
The current _AddRuntimeAssertionsForInlineConstraintsPass has 2 known issues caused by its use of torch.fx.Interpreter:
1. SymInt-related ops (e.g. item()) are executed, causing new Unbacked SymInts to appear in the graph during the pass.
2. The graph is reconstructed, and node names/indices can be different from before, causing mismatches with `module_call_graph`, and leading to issues during unflattening.
This refactors the pass to use PassBase instead of _ExportPassBaseDeprecatedDoNotUse, only constructing new nodes for assertions.
Test Plan: This pass is called on all strict-mode export calls with range_constraints, test that behavior remains unchanged.

This PR ensures that assignment of attributes of primitive type work without needing any code changes in non-strict mode. (In a previous PR we banned attribute assignments of tensor type unless such attributes are registered as buffers.)
While strict mode errors on (all) attribute assignments, non-strict doesn't care, so one might assume that this kind of attribute assignment should already work in non-strict. However, there's a problem: we run through the program once for metadata collection and then run through it again for tracing, so the values observed during tracing (and potentially burned into the graph) do not reflect what should have been observed had the metadata collection pass not run.
So the only thing this PR needs to do is restore values of assigned attributes of primitive type once the metadata collection pass has run. We do this by moving the attribute assignment detecting context manager from the overall `aot_export` call in `_trace.py` to the metadata collection pass in `aot_autograd.py`, and extending it. The rest of the PR moves some utils around.

This PR propagates node names to higher-order-op subgraph placeholders, retaining the top-level names and handling naming collisions by suffixing other non-placeholder nodes in the subgraph with an index. This is the same handling as in fx.Graph/fx.Node, but implemented separately as a pass.
Since the input schemas of HOO subgraphs are very different, they are enumerated in _name_hoo_subgraph_placeholders(). Currently cond, map_impl, and wrap_with_set_grad_enabled are handled, but other ops can be easily added.

In non-strict, assignment of attributes in a model causes their state to contain fake tensors post-tracing, which leads to incorrect results on running the exported model. We now error when this happens, asking the user to use buffers instead.
Next, we add support for assignment of buffers. The final values of the buffers turn into outputs of the graph. Since the buffers are already lifted as inputs and populated with the initial values when the model is run, this leads to a simple programming model where the driver of the model can feed the outputs back as inputs for successive runs.

Previously, `node.meta["nn_module_stack"]` had type `Dict[str, Tuple[str, class]]` when exported, and later `Dict[str, Tuple[str, str]]` after de/serialization. This PR changes it to consistently be `Dict[str, Tuple[str, str]]` for round-trippability, i.e.
```
{..., 'L__self___conv': ('conv', 'torch.nn.modules.conv.Conv2d')}
```
`source_fn_stack` is left untouched in this PR.
note: the `Union[type, str]` type annotations in ONNX are because ONNX goes through both `export.export()` and `_dynamo.export()` (which still has the original `Dict[str, Tuple[str, class]]` format). nn_module_stack from `export.export()` should consistently have the new format, and we verify/test for that in `_trace.py`.

Summary:
This PR restores original names to placeholder nodes, replacing the default names arg0_1, arg1_1, and so on.
User inputs now follow the signature of mod.forward(), for example forward(x, y) produces nodes x, y. If the tensors are nested in dictionaries, lists, tuples, or dataclasses, the names are a concatenation of the path to the tensor, e.g. x = {'a': torch.randn(4), 'b': [torch.randn(4), torch.randn(4)]} produces nodes x_a, x_b_0, x_b_1.
Parameters, buffers, constants, and custom objects follow the FQN of the object, prefixed by "p", "b", "c", and "obj" respectively. For example, self.bar.l0.weight gets you p_bar_l0_weight.
Effect tokens are named token_1, token_2, and so on, since they are not grounded in model inputs or named attributes.

- stack_trace is currently missing from nodes in non-strict export
- in strict mode, stack_trace is populated for placeholder nodes, which may not be well-defined (with multiple uses)
We filter the call stack during tracing for calls from forward() methods, or ops in `torch.__init__.py` (e.g. sym_size_int, sym_constrain_range, etc.) to populate stack_trace. A node-level check is also added to _export_non_strict().

Currently when there is a print/warning in the graph, dynamo graph breaks causing export to fail. However export would like to just skip over these print/warning calls: https://github.com/pytorch/pytorch/issues/113792.
Additionally there's a torch.compile feature request to "reorder prints" so that instead of graph breaking when hitting prints/logging, we can skip over these prints to create larger compiled graphs, and then print the results out after those compiled graphs: https://github.com/pytorch/pytorch/issues/93739.

There are some limitations to the printing right now:
* You can only register logging functions, not methods
* Inputs to the logging functions can only be tensors, constants, and format strings
* Inputs to the logging functions which will later be mutated in-place will not be printed correctly
TODO: Add the following tests
* print function with argument of nested data structure;
* print function with argument of nested data structure being updated inside of compile region (this would test if we handle side effect correctly);
* custom defined logging functions with nn.Module or nn.Module attribute arguments;
* custom defined logging functions with submodule input/output as arguments (we need to handle the mapping and fused-out value);
