Filtering out the stacktrace so that the stacktrace on nodes when using fx.Tracer looks nicer. I just copied the filtering we have in [proxy_tensor.py](6720d23969/torch/fx/experimental/proxy_tensor.py (L1903-L1931)).
Previously the stacktrace looked like:
```
File "/data/users/angelayi/pytorch/moo.py", line 3964, in <module>
run_tests()
File "/data/users/angelayi/pytorch/torch/testing/_internal/common_utils.py", line 1342, in run_tests
unittest.main(argv=argv)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/main.py", line 101, in __init__
self.runTests()
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/main.py", line 271, in runTests
self.result = testRunner.run(self.test)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/runner.py", line 184, in run
test(result)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/suite.py", line 84, in __call__
return self.run(*args, **kwds)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/suite.py", line 122, in run
test(result)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/suite.py", line 84, in __call__
return self.run(*args, **kwds)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/suite.py", line 122, in run
test(result)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/case.py", line 650, in __call__
return self.run(*args, **kwds)
File "/data/users/angelayi/pytorch/torch/testing/_internal/common_utils.py", line 3324, in run
self._run_custom(
File "/data/users/angelayi/pytorch/torch/testing/_internal/common_utils.py", line 3296, in _run_custom
super_run(result=result)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/case.py", line 591, in run
self._callTestMethod(testMethod)
File "/home/angelayi/.conda/envs/pytorch-3.10/lib/python3.10/unittest/case.py", line 549, in _callTestMethod
method()
File "/data/users/angelayi/pytorch/torch/testing/_internal/common_utils.py", line 3156, in wrapper
method(*args, **kwargs)
File "/data/users/angelayi/pytorch/moo.py", line 1495, in test_stack_trace
gm = torch.fx.GraphModule(m, tracer.trace(m))
File "/data/users/angelayi/pytorch/torch/fx/_symbolic_trace.py", line 837, in trace
(self.create_arg(fn(*args)),),
File "/data/users/angelayi/pytorch/moo.py", line 1485, in forward
x = x * 2
File "/data/users/angelayi/pytorch/torch/fx/proxy.py", line 716, in impl
return tracer.create_proxy("call_function", target, args, kwargs)
File "/data/users/angelayi/pytorch/torch/fx/proxy.py", line 248, in create_proxy
proxy.node.stack_trace = "".join(CapturedTraceback.extract().format())
```
Now it looks like:
```
File "/data/users/angelayi/pytorch/moo.py", line 1485, in forward
x = x * 2
```

## What's the problem?
The popular `fx.node.map_arg()` and `fx.node.map_aggregate()` apply operations recursively on `dict`s, `tuples`, `list`s, etc, and return a new collection of the same type.
Unfortunately, their base input type is `Argument`, which is [very unspecific indeed](5d55a6585d/torch/fx/node.py (L48-L58)): most type information is just thrown away at the call site of either of these functions, as far as the type checker goes.
As `torch` moves to a more typed code base, this would force innocent, unsuspecting developers to add logically unnecessary casts or `# type: ignore` statements.
## What's the solution?
Making these two `node.map_*` functions generic on the first argument and return type means that type information is preserved for the type checker. (The signature of the other parameter, the function that visits the nodes and subnodes, has not changed, nor should it.)
## Won't it break everything?
It doesn't break the type checker - one place needed an extra hint.
There have been code breakages, resolved one, at least one new one... we'll see!

Summary: ShapeProp doesn't know how to propagate unbacked. Patch it up to propagate unbacked symints like PropagateUnbackedSymInts.
Test Plan:
```
buck run mode/dev-nosan fbcode//caffe2/test:fx -- -r test_shape_prop_unbacked_sym
```

Add similar semantics for creating a buffer object similar to creating a parameter. This is done by introducing a new Buffer class that can be used for type disambiguation. The underlying functionality of registering a buffer remains the same as the register_buffer method has not been changed. The persistent parameter in the Buffer type is to indicate whether a buffer object should be persistent or not. Other non-test changes have to do with getting the new Buffer type recognized by inductor and dynamo. Remaining changes are test changes to make sure that the Buffer type can be used as a drop in replacement for register_buffer as it just leads to register_buffer being called. The addition of this new functionality still allows for normal tensors to be used as buffers so these changes are intended to be backwards compatible.

was failing with a complaint about infinite recursion. Fixed that and then marked the two API changes from #123681 as private (for `get_example_value`) and backward compatible (for `insert_deferred_runtime_asserts`).

UnflattenedModule doesn't really behave like a graph module; we customize `__call__` to do something completely different than what GraphModule does. So, things that test `isinstance(unflattened_module, GraphModule)` and do something with the GraphModule are often broken.
This change makes UnflattenedModule it's own thing.
