fix static dispatch linker error (#53859)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/53859
The redispatch API wasn't linking properly when static dispatch is enabled. I'm still not sure why this wasn't caught by the static dispatch test in CI- maybe, as swolchok pointed out, we have a flag set somewhere that defers undefined symbols until runtime.
Before, building with static dispatch enabled locally + running `import torch` gave me this error:
```
>>> import torch
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/raid/hirsheybar/pytorch/torch/__init__.py", line 197, in <module>
from torch._C import *
ImportError: /raid/hirsheybar/pytorch/torch/lib/libtorch_cpu.so: undefined symbol: _ZN2at10redispatch11logical_or_EN3c1014DispatchKeySetERNS_6TensorERKS3_
>>>
```
Printing the symbol:
```
(pytorch) hirsheybar@devfair017:/scratch/hirsheybar/pytorch$ c++filt _ZN2at10redispatch11logical_or_EN3c1014DispatchKeySetERNS_6TensorERKS3_
at::redispatch::logical_or_(c10::DispatchKeySet, at::Tensor&, at::Tensor const&)
```
Sure enough, the functions defined in `RedispatchFunctions.cpp` don't have the DispatchKeySet argument included. Adding them in this PR.
