Graph partition analyzes read_writes to get partition input names. However, weak dep is fake dependency and is not actually read or written. So we should not include weak dep in graph partition input names.
The following test failure is fixed by removing weak dependency from partition_input_names:

Operations performed on tensors with `requires_grad=True` such as
```python
import torch
x = torch.tensor(2.0, requires_grad=True)
y = x ** 3
```
and
```python
x = torch.tensor(2.0, requires_grad=True)
y = torch.pow(x,3)
```
are valid operations.
While an operation using `numpy` like
```python
import numpy as np
x = torch.tensor(2.0, requires_grad=True)
y = np.pow(x,3)
# > RuntimeError: Can't call numpy() on Tensor that requires grad. Use tensor.detach().numpy() instead.
```
leads to an error.
However, an operation that uses `math` like
```python
import math
x = torch.tensor(2.0, requires_grad=True)
y = math.pow(x,3)
```
does not cause an error, and `y` is no longer a tensor with a gradient!
This represents a [footgun](https://en.wiktionary.org/wiki/footgun#Noun) for some users, like myself when training small, custom, non-neural network models.
To prevent future undesired behavior, I added a warning when converting tensors with `requires_grad=True` to scalars. Now, when using `math.pow` on a `tensor`, we get a single warning with:
```python
x = torch.tensor(2.0, requires_grad=True)
y = math.pow(x,3)
# > UserWarning: Converting a tensor with requires_grad=True to a scalar may lead to unexpected behavior.
# Consider using tensor.detach() first.
```

Adds feature for #98925
Tests pass for both existing reflectionpad2d and the new one I inserted.
**Summary of the work:**
Simple conditional check for deterministic mode that will dispatch to a different kernel. This kernel does not use any atomic operations, and will lead to deterministic results as instead of going from the output to input(1:1) relationship, I am doing the opposite. I am going from input -> all outputs, which is 1 to many. These operations are done in the same order every execution as I simply traverse the data set with a grid stride loop and use simple linearized indexing into the input tensor.
So each thread will compute the 4 conditionals, which are then used to see if the input has an output in the 8 regions. These 8 regions are top left, top, top right, left, right, bottom left, bottom, bottom right`.
I did not focus on performance for this PR as that would expand the scope heavily. If there are any performance questions though i can answer.

Triton 2.2 and greater have a bug where allowing TF32 generation for a GPU that does not support TF32 will cause code generation errors. Patch around this problem by:
1. Adding a function to `torch.cuda` that determines whether CUDA hardware is capable of using the TF32 format.
2. Using that function to explicitly disable TF32 generation when calling Triton, where needed.
To demonstrate that this fix works, try running `test/inductor/test_max_autotune.py` on a GPU with CUDA compute capability < 8 (e.g. any NVIDIA consumer GPU) without this fix.

For #143486
Interestingly enough changing the indexing type seems to degrade performance when a larger width is not needed, even on small sizes, so making this a template param rather than forcing all cases to 64-bit

Step required for performance in #143122
Adds support for CPU scalar for tensor_2 in addcmul. For example:
```
import torch
a = torch.rand(2, 2, device="cuda")
b = torch.tensor(1e-3)
torch.add(a, b)
torch.addcmul(a, a, b) # used to fail, now works

Fixes a bug introduced in https://github.com/pytorch/pytorch/pull/137267
While the test ensures the finalizer did run to make sure things are cleared, the objects are not properly collected by the gc due to the faulty tp_clear implementation. So, while the finalizer did run, the object was still alive.
Fixing this by giving tp_clear the same treatment as tp_traverse and tp_dealloc on Tensor: make it a unique function that handles the full subclass hierarchy in one place.

On ROCm, hipification converts std::min to ::min, but ::min is not returning the right result. This impacts index_add_ operation on a large tensor, we end up picking the large values instead of max supported block size (128). This leads to GPU accessing memory out of bounds.
While we wait for ::min to be fixed, we can use < operator to compare instead of relying on ::min.
Example Code w/ failure:
```
D=6144
hidden_states = torch.zeros([16384, 6144], device="cuda:0", dtype=torch.bfloat16)
index = torch.randint(0, 16384, (1, 32, 16384), device="cuda:0", dtype=torch.int64)
output = torch.empty([1, 32, 16384, 6144], device="cuda:0", dtype=torch.bfloat16)
hidden_states.index_add_(0, index.view(-1), output.view(-1, D))
```
```
Traceback (most recent call last):
