Resolved docstring errors as listed. I initially changed in the main branch of forked repo which caused changes to appear in my PR to other issue. I have fixed that and hope this PR won't have any conflicts.
Kindly review @svekars @jbschlosser.
In case of any other issues please let me know. Thanks!

### Discussion
- `has_complex` shortcut provides additional 2x dynamo speedup. It is not necessary to achieve a significant overall speedup.

Starts addressing #106802
This PR also conveniently does some BE:
- Fixes a bug in adamw where we use amsgrad instead of per group amsgrad
- Brings the impls of adamw and adam closer to correctness and to each other
I couldn't fully remove the .pyi's because mypy was going to complain about the entire files which scared me and shouldn't go in this PR anyway.
Test plan:
- Add tests to ensure that lr could be passed as a Tensor
- Did some profiling of the below code (runs 1k iterations of step for Adam)
```
import torch
from torch.testing._internal.common_utils import TestCase
param = torch.rand(2, 3, dtype=torch.float, device='cuda:0', requires_grad=True)
param.grad = torch.rand_like(param)
lr = torch.tensor(.001, device='cuda:0')
opt = torch.optim.Adam([param], lr=lr, fused=True)
with torch.profiler.profile(
activities=[
torch.profiler.ProfilerActivity.CPU,
torch.profiler.ProfilerActivity.CUDA,
]
) as p:
for _ in range(1000):
opt.step()
print(p.key_averages().table(sort_by="cpu_time_total"))
```

After my change (notice there are no d2h syncs and the CPU time is lower!):
Next steps long term:
- have all capturable foreach + forloop impls in Adam(W) handle tensor LR

There are extra graph compilations on XLA when beta{1,2} ** step get too small. This PR addresses this issue by making the `capturable` interface enabled for XLA, as well as switching to `torch.float_power` which preserves the same behaviour as the non-capturable flow on XLA.

Starts addressing https://github.com/pytorch/pytorch/issues/97712 by
- Minimizing intermediates usage for foreach Adam
- Document the extra memory usage
- Add comments within the code for clarity now that we reuse intermediates
- Add tests
- Did some refactoring
Next steps involve doing this for all other foreach implementations. Note that even after this change, foreach mem usage will be higher than forloop due to the fact that we have a minimum budget of 1 intermediate (to not muddle the input values) and the intermediate will be larger. For capturable, the memory usage is higher due to moving more tensors to CUDA.

This is a reland of https://github.com/pytorch/pytorch/pull/100007 with a build fix for Windows debug builds.
`at::native::ParamsHash` only works on structs with standard layout, but `std::string` isn't one in Visual C++ debug builds, which one can easily verified by running something like:
```cpp
#define _DEBUG
#include <type_traits>
#include <string>
static_assert(std::is_standard_layout_v<std::string>, "Oh noes");
```
If above conditon is not met, instead of printing a static_assert output, VC++ raises a very cryptic compilation errors, see https://github.com/pytorch/pytorch/pull/100007#discussion_r1227116292 for more detail.
Also, using `std::hash` for string should result in a faster hash function.

This pull request introduces a new function `_group_tensors_by_device_and_dtype` that can group tensors by their device and dtype, and updates the `foreach` utilities and several optimizers to use this function. The goal is to improve the performance, readability, and compatibility of the code that handles tensors with different properties. The pull request also adds a test case and type annotations for the new function, and some error checks for the `fused` argument in Adam and AdamW.

Fixes#95781.
The cause seems to be that the current implementation doesn't correctly pass `found_inf` when `grad_scale` is `None`. Therefore parameters can get mistakenly updated by gradients whose some elements are invalid, i.e. nan or inf.

Big OOP correction continued. Also added a test this time to verify the defaulting was as expected.
The key here is realizing that the grouping for foreach already assumes that the non-param tensorlists follow suit in dtype and device, so it is too narrow to check that _all_ tensors were on CUDA. The main leeway this allowed was state_steps, which are sometimes cpu tensors. Since foreach _can_ handle cpu tensors, this should not introduce breakage.

Rolling back the default change for Adam and rectifying the docs to reflect that AdamW never defaulted to fused.
Since our fused implementations are relatively newer, let's give them a longer bake-in time before flipping the switch for every user.

This allows it so that ONLY when the users don't set anything for foreach or fused do we switch the default and cascades adam so that we default to fused, then foreach, then single-tensor.
To clarify:
* if the user puts True in foreach _only_, it will run the foreach implementation.
* if the user puts True in fused _only_, it will run the fused implementation.
* if the user puts True in foreach AND for fused, it will run the fused implementation.
And:
* if the user puts False in foreach _only_, it will run the single tensor implementation.
* if the user puts False in fused _only_, it will still run the single tensor implementation.
* if the user puts False in foreach AND for fused, it will run the single tensor implementation.
I also didn't trust myself that much with the helper function, so I ran some local asserts on _default_to_fused_or_foreach. The only point left to really test is the type(p) -- torch.Tensor but I think the distributed tests will catch that in CI.

@mlazos: skips `item()` calls if compiling with dynamo, by defining a helper function `_get_value` which either returns the result of `.item()` or the scalar cpu tensor if compiling with dynamo. This was done because removing `item()` calls significantly regresses eager perf. Additionally, `_dispatch_sqrt` calls the appropriate sqrt function (math.sqrt, or torch.sqrt).

### Description
Across PyTorch's docstrings, both `callable` and `Callable` for variable types. The Callable should be capitalized as we are referring to the `Callable` type, and not the Python `callable()` function.
### Testing
There shouldn't be any testing required.

Generator comprehensions with any/all are less verbose and potentially help to save memory/CPU : https://eklitzke.org/generator-comprehensions-and-using-any-and-all-in-python
To make JIT work with this change, I added code to convert GeneratorExp to ListComp. So the whole PR is basically NoOp for JIT, but potentially memory and speed improvement for eager mode.
Also I removed a test from test/jit/test_parametrization.py. The test was bad and had a TODO to actually implement and just tested that UnsupportedNodeError is thrown, and with GeneratorExp support a different error would be thrown.

This is causing issues if the user has the step on cuda for a good reason.
These assert prevents code that used to run just fine to fail.
Note that this is a pretty bad thing to do for performance though so it is ok to try and push users away from doing it.
For the 1.12.1 milestone: this is not asking for a dot release to fix this (as this is bad practice anyways). But it would be a great thing to add if we do one: it is very low risk and will prevent breakage for users.

Near term fix for https://github.com/pytorch/pytorch/issues/76368.
Q. Why does the user need to request `capturable=True` in the optimizer constructor? Why can't capture safety be completely automatic?
A. We need to set up capture-safe (device-side) state variables before capture. If we don't, and step() internally detects capture is underway, it's too late: the best we could do is create a device state variable and copy the current CPU value into it, which is not something we want baked into the graph.
Q. Ok, why not just do the capture-safe approach with device-side state variables all the time?
A. It incurs several more kernel launches per parameter, which could really add up and regress cpu overhead for ungraphed step()s. If the optimizer won't be captured, we should allow step() to stick with its current cpu-side state handling.
Q. But cuda RNG is a stateful thing that maintains its state on the cpu outside of capture and replay, and we capture it automatically. Why can't we do the same thing here?
A. The graph object can handle RNG generator increments because its capture_begin, capture_end, and replay() methods can see and access generator object. But the graph object has no explicit knowledge of or access to optimizer steps in its capture scope. We could let the user tell the graph object what optimizers will be stepped in its scope, ie something like
```python
graph.will_use_optimizer(opt)
graph.capture_begin()
...
```
but that seems clunkier than an optimizer constructor arg.
I'm open to other ideas, but right now I think constructor arg is necessary and the least bad approach.
Long term, https://github.com/pytorch/pytorch/issues/71274 is a better fix.

Here's the command I used to invoke autopep8 (in parallel!):
git ls-files | grep '\.py$' | xargs -n1 -P`nproc` autopep8 -i
Several rules are ignored in setup.cfg. The goal is to let autopep8
handle everything which it can handle safely, and to disable any rules
which are tricky or controversial to address. We may want to come back
and re-enable some of these rules later, but I'm trying to make this
patch as safe as possible.
Also configures flake8 to match pep8's behavior.
Also configures TravisCI to check the whole project for lint.
