This PR:
- Corrects the forward AD formula of `torch.sgn`.
- The reason why we can't use `auto_element_wise` for this operations is rather subtle. I left a comment.
- This, in turn, fixes a problem we had in forward-over-backward for `linalg.svd` and other spectral decompositions (and `norm`, `linalg.norm`, `linalg.matrix_norm`) that were using `torch.abs` (whose derivative is given by `torch.sgn`.
- Implement the formula for a number of missing operations `nansum`, `amax`, `amin`...
- Simplified a few formulas, most notably the forward AD for `div` and the derivative of `norm`, `linalg.norm` and `vector_norm` for `ord=+-inf`.
- Correct the formula for `mean`, `std_mean`, `var_mean` when `dim` is provided and equal to `()` (or `None`)
- A few minor improvements to `sum_backward`, `unsqueeze_multiple` and formulas depending on them
- Fix the derivatives of `std_mean` and `std_var` (complex support,
ASAN, forward AD...)

`chalf` is experimental as the op coverage is low.
Following script raises 6 warnings if `set_warn_always(True)` else raises only 1 warning.
```python
import torch
torch.set_warn_always(True)
device='cpu'
t = torch.randn(3, dtype=torch.chalf, device=device)
y = torch.rand(3, dtype=torch.chalf, device=device)
# Allocates new tensor for result
t + y
device='cuda'
t = torch.randn(3, dtype=torch.chalf, device=device)
y = torch.rand(3, dtype=torch.chalf, device=device)
# Allocates new tensor for result
t + y
```

Summary:
While running those tests on
- my local windows GPU machine
- a dev server
- an on-demand GPU
I noticed a few test failures and here's some tentative fixes
Test Plan:
Ran tests on:
- my local windows GPU machine
- a linux dev server w/o GPU
- an linux on-demand GPU server
Note that when using CUDA11, the tests crashes (segfaults) on calls to torch.nn.ConvTranspose3d. Fails on master, but works with CUDA10.

Fixes#73298
I don't know whether `where` kernel actually supports type promotion, nor am I in the mood to find out, so it's manual type promotion.
Edit: nah, i can't tell TI to "promote to common dtype" because of bool condition, so manual type promotion is our only option.
I'll see what tests start failing and fix.
Uses some parts from #62084

crossref is a new strategy for performing tests when you want
to run a normal PyTorch API call, separately run some variation of
the API call (e.g., same thing but all the arguments are meta tensors)
and then cross-reference the results to see that they are consistent.
Any logic you add to CrossRefMode will get run on *every* PyTorch API
call that is called in the course of PyTorch's test suite. This can
be a good choice for correctness testing if OpInfo testing is not
exhaustive enough.
For now, the crossref test doesn't do anything except verify that
we can validly push a mode onto the torch function mode stack for all
functions.

Update signature of `scatter_reduce_` to match `scatter_/scatter_add_`
`Tensor.scatter_reduce_(int64 dim, Tensor index, Tensor src, str reduce)`
- Add new reduction options in ScatterGatherKernel.cpp and update `scatter_reduce` to call into the cpu kernel for `scatter.reduce`
- `scatter_reduce` now has the same shape constraints as `scatter_` and `scatter_add_`
- Migrate `test/test_torch.py:test_scatter_reduce` to `test/test_scatter_gather_ops.py`

Summary:
This PR ports several tests in `test/test_torch.py` over to OpInfo ErrorInputs.
Some tests commented "convert to ErrorInputs" still remain in `test_torch.py`. They fall under two categories:
- Memory overlap tests which specifically test the in-place version of an operator (e.g. [this test](424a054d53/test/test_torch.py (L3788)) for index_add_).
- Tests with non-trivial behavior calling `torch.cuda.synchronize()` after calling the operator being tested (e.g. [this test](424a054d53/test/test_torch.py (L4948)) for torch.multinomial).
