Summary:
In general, device_ is not very useful in OpKernel. Remove it to avoid misuse.
Also, the meaning of `device_` is also ambiguous in the OpKernel.
For StaticDispatch kernels, we always call cpu kernel.
For C10Kernel, we rely on input tensor's device and dispatcher to determine which device to run on.
For ops involves multiple device, e.g. aten._to_copy(device), the meaning of device is ill-defined.

And prevent new ones from appearing by removing `-Wno-error=extra-semi` (not sure what was thereason behind adding the warning but not erroring on on it when building with -Werror introduced by https://github.com/pytorch/pytorch/pull/140236 )
300+ violations of that rule were fixed by running `sed -i -e "s/});/})/" /` against `torch/nativert`
Other 3p deps that needs updates:
- TensorPipe
- LLVM
- FBGEMM
