Extend from #165430
* #165903(Clean up for graph break)
* ->#165745
* #165430
One main refractor from the previous PR:
* For assertions like checking `len(args)` or `len(kwargs)`, using `raise_args_mismatch` instead of `raise_type_error_exc`
I am also considering moving `raise_type_error_exc` into `utils.py` for consistency.

This is needed because if we codegen cells for nested frames AFTER side effects, then reconstruction could get messed up. From below:
>The added test case demonstrates the reconstruction failure if we kept cell codegen at the original place (only happens with nested graph breaks since we reconstruct nested frame cells from VariableTracker rather than directly using LOAD_CLOSURE).
>At a high level, what happened before this change was that side_effects was pruning the cells (I don't recall exactly why this happens), and because cells were codegen'd after the side effects were applied, we were unable to properly reconstruct the cell. The error I was seeing was a list/tuple IndexError.

Implements https://github.com/pytorch/pytorch/issues/144908.
Implementation notes:
- `set_fullgraph` is implemented using `patch_config`, which changes config correctly during runtime and tracing.
- Moved setting `config.error_on_graph_break` from convert_frame.py to eval_frame.py. This is because this should only be done at the top-level decorated function. If we kept this in convert_frame.py, we would be changing `config.error_on_graph_break` on every top-level frame, which causes confusing behavior (see added test for example).
- InstructionTranslator reads from `config.error_on_graph_break` every `step()`. This is to determine the value of `config.error_on_graph_break` at the time of the graph break, because tracer cleanup will restore the value of `config.error_on_graph_break` .
- `convert_frame.py` determines whether we should abort tracing (fullgraph=True) or continue (fullgraph=False) by reading the value of the tracer's `error_on_graph_break`. If there is no tracer (failed to initialize), then default to reading `config.error_on_graph_break`.

`torch.compile` now always goes through `torch._dynamo._optimize`. fullgraph is now implemented in `torch.compile` by looking at `config.error_on_graph_break`. Export still goes through `torch._dynamo._optimize_assert`, which uses `tx.one_graph` instead of `config.error_on_graph_break`.

This word appears often in class descriptions and is not consistently spelled. Update comments and some function names to use the correct spelling consistently. Facilitates searching the codebase.

The reason why we did this before is because that's how our older
autograd.Function x Dynamo interaction work, but we've since adopted
newer designs that don't actually need the autograd.Function.ctx proxied
into the graph.
We still need a fx.Proxy for the autograd.Function.ctx object, so
whenever we do I create one via discard_graph_changes.

This fixes most of the "torch.compile X tensor-subclass" issues
encountered in https://github.com/city96/ComfyUI-GGUF/issues/118. The
relevant tensor subclass definition is here:
298192ed60/ops.py (L18-L65).
A few things to note about the tensor subclass:
1. it overrides a lot of the `torch.Tensor` methods (e.g., `to`,
`clone`), so this patch updates `TensorWithTFOverrideVariable.var_getattr`
to support that.
2. it overrides the `shape` property, so this patch updates
`TensorWithTFOverrideVariable.var_getattr` to support property as well.
3. it has calls to `torch.Tensor.size`, which returns `torch.Size`,
which gets reconstructed in `torch.Tensor.__torch_function__`, so
this patch adds support for calling `torch.Size(...)` on non-constant
inputs.

This fixes most of https://github.com/huggingface/diffusers/issues/10795,
except for `torch.Tensor._make_subclass`, which will be fixed in a
subsequent patch.
The relevant tensor subclass from the aforementioned issue is defined
here: fbf6b856cc/src/diffusers/quantizers/gguf/utils.py (L398-L435).
There are two things to note about the tensor subclass:
1. it calls `super().__torch_function__`, which is
`torch._C._disabled_torch_function_impl`, so this patch updates
`SuperVariable.call_method` to handle it (we can't do a simpler
polyfill due to some bug with `var_getattr` raising
`NotImplementedError`, which forgot to restore symbolic context).
2. it sets and reads attributes (`quant_type`), and
defines new methods (`as_data`), so this patch adds support for those.
3. it has a `__init__`, which Dynamo needs to trace through in
`TensorSubclassVariable.call_function`.
