Tracking issue: #138399
This PR fixes a number of reference implementations (which are also used as meta
functions), making them more consistent with CPU device. More specifically, it fixes those
operations that use `_make_elementwise_unary_reference` decorator, and don't error on
mismatching out argument dtype while they error when using concrete devices (e.g. CPU).
The fixed operations are:
- `abs`
- `ceil`
- `floor`
- `frac`
- `isneginf`
- `isposinf`
- `sgn`
- `sign`
- `signbit`
- `trunc`

This PR replaces the parameter names specified in the `triangular_solve_meta`
function (specifically in its `@out_wrapper(...)` decorator) by those written in the
_native_functions.yaml_ file.
This name mismatch caused the operation to fail when using the meta device (see error
below):
```python
Traceback (most recent call last):

This PR introduces an `OpInfo` test that checks whether running each `out=` operation
using meta inputs is consistent with using concrete (e.g. CPU) inputs. More specifically,
it tests the case where the output tensors are not of the expected data type. According to
the `out=` specification, some operations should error.
I have added XFAIL to the set of operations that are currently failing.

See #121528 for additional context.
In #120682, we moved the attention kernels from meta_registrations to fake_impls with the intent of fixing the device handling for seed/offset: these are typically on CPU. We needed to put the registrations in fake_impls to do this because meta_registrations doesn't have a way to specify device, whereas fake_impls does. But when we tried to actually fix the device types (#120839), we had to revert the PR because it broke cudagraph handling (during which seed/offset _are_ on CUDA).
Now, we want to put the registrations back in meta_registrations so that we can call these kernels with meta tensors. The use case is later in this stack - we want to be able to use the flop counter with these kernels.
Also - I specifically skip the `compare_tensor_meta()` check in test_fake / test_fake_autocast tests for the `_efficient_attention_forward` and `_flash_attention_forward` kernels, which fails because of the device mismatch from the seed/offset tensors. Then we can un-skip these opinfos. I verified that the efficient_attention_forward bug (#120842) is now caught by these opinfos if I revert the fix from this PR.

torch.cuda.amp.autocast / torch.cpu.amp.autocast are deprecated and spew a ton of warnings when these tests run. This PR: Update to just use torch.amp.autocast(device).
Note: this uncovers a bug in the test: when `device` is CUDA, it actually shows up as "cuda:0" - so previously, this test was _always_ using `torch.cpu.amp.autocast` even for `cuda` device. This PR fixes this, and uncovers additional bugs in `pinverse` and `linalg.pinv`; `linalg.pinv` was already failing before on CPU, but now the test also catches failures on CUDA, (and this PR adds to the skipped-test list).

Follow-up to #113118 and #124306.
Developed in coordination with the solution to https://github.com/microsoft/onnxscript/pull/1547
This PR adds the missing fake tensor implementation for `aten.unique_dim`, thus enabling tracing and compilation of `torch.unique` when `dim` is not None.
Local testing has proceeded with the following simple script (provided that one has checked out the changes in https://github.com/microsoft/onnxscript/pull/1547):
```python
import onnx
import onnxruntime as ort
import logging
import numpy as np
onnx_program = torch.onnx.dynamo_export(
lambda x: torch.unique(x,
dim=0,
return_inverse=True),
torch.arange(10),
export_options=torch.onnx.ExportOptions(
dynamic_shapes=True,
diagnostic_options=torch.onnx.DiagnosticOptions(
verbosity_level=logging.DEBUG)))
onnx_program.save("torch_unique.onnx")
onnx_inputs = onnx_program.adapt_torch_inputs_to_onnx(torch.arange(10))
onnx_outputs = onnx_program(*onnx_inputs)
loaded_onnx_program = onnx.load("torch_unique.onnx")
onnx.checker.check_model(loaded_onnx_program)
ort_session = ort.InferenceSession("torch_unique.onnx")
inputs = np.random.randint(0, 10, 10)
print(f"Inputs: {inputs}")
outputs = ort_session.run(None,

Closes #120988
Currently operators that hit the autograd fallback call `check_inplace`
on all mutated inputs, including out arguments. This leads to a slightly
confusing error message:
```
RuntimeError: a leaf Variable that requires grad is being used in an in-place operation.
```
Compared to functions that don't fallback, which raise
```
RuntimeError: add(): functions with out=... arguments don't support automatic differentiation, but one of the arguments requires grad.
```
This changes the error message to make clear the issue is with the out argument,
but does not tighten the check to outright ban out arguments that require grad.
Instead, I use the same checks from `check_inplace` which allows non-leaf tensors
that require grad to pass without error.

Replaces `view_func()` closures with a reified `ViewFunc` data structure. Codegen generates a `ViewFunc` subclass for each view op (e.g. `NarrowViewFunc`) containing state needed to reconstruct the view. The `ViewFunc` API allows for querying and hot-swapping any `SymInt`s or `Tensors` in the state through `get_symints()` / `get_tensors()` / `clone_and_set()`, which will be essential for fake-ification later on.
```cpp

Part 2 of implementation for general [subclass view fake-ification](https://docs.google.com/document/d/1C5taWiplmX7nKiURXDOAZG2W5VNJ2iV0fQFq92H0Cxw).
Details:
* Codegen `rev_view_func()` alongside `view_func()`
* Reverse view_func gives you a "base" from a "view": `rev_view_func(new_view) -> new_base` AKA it plays the original view backwards
* Utilizes the functional inverses defined in `FunctionalInverses.cpp`, passing `InverseReturnMode::AlwaysView`
* Manually implements functional inverses for `narrow()` and `chunk()`
* **NB: Multi-output views now set view_func() / rev_view_func() for each of the output views!**
* Due to this, the `as_view()` overload that operates on a list of views is scrapped in favor of iteration via codegen
Example codegen in `ADInplaceOrViewTypeN.cpp`:
```cpp
at::Tensor narrow(c10::DispatchKeySet ks, const at::Tensor & self, int64_t dim, c10::SymInt start, c10::SymInt length) {
auto _tmp = ([&]() {
at::AutoDispatchBelowADInplaceOrView guard;
return at::_ops::narrow::redispatch(ks & c10::after_ADInplaceOrView_keyset, self, dim, start, length);
})();
std::function<at::Tensor(const at::Tensor&)> func=nullptr;
std::function<at::Tensor(const at::Tensor&)> rev_func=nullptr;
if (false || !self.unsafeGetTensorImpl()->support_as_strided() ||

Updates flake8 to v6.1.0 and fixes a few lints using sed and some ruff tooling.
- Replace `assert(0)` with `raise AssertionError()`
- Remove extraneous parenthesis i.e.
- `assert(a == b)` -> `assert a == b`
- `if(x > y or y < z):`->`if x > y or y < z:`
- And `return('...')` -> `return '...'`

Cell In[7], line 1
----> 1 torch.ops.aten.reshape.default(self=torch.rand(1,2), shape=[2])
TypeError: OpOverload.__call__() got multiple values for argument 'self'
```
# Where's the problem?
1. the aten ops first arg is usually named `self` (aten/src/ATen/native/native_functions.yaml)
2. Unfortunately, in `torch._ops.{OpOverload, OpOverloadPacket}.__call__()`, the first arg is (by python convention) named `self` too.
So when call `self` by kwargs, `OpOverloadPacket.__call__` received:
```
OpOverloadPacket.__call__(self, {"self": ...})
```
It is Python that does not allow some argument named "arg" to appear twice. and hence
> TypeError: OpOverload.__call__() got multiple values for argument 'self'
# How to fix?
**Note that**, in above, `self` is an instance of `OpOverloadPacket`, and the "self" kwarg is the input tensor to the aten op. To fix, we only need to differentiate the two `self`s.
In Python, first arg of a method does not need to be named `self`. So we change the `__call__` definition to:
```
def __call__(_self, ...):
```
Now the call becomes:
```
OpOverloadPacket.__call__(_self, {"self": ...})
```
where:
* `_self` is the instance to the `OpOverloadPacket`
* `"self"` is the input tensor to the aten op.
Test Plan:
```
In [4]: [x.name for x in torch.ops.aten.reshape.default._schema.arguments]

In [3]: torch.ops.aten.reshape.default(self=torch.rand(1,2), shape=[2])
