Remove runtime dependency on ATen/native/vulkan/impl (#2270)

Summary:
Pull Request resolved: #2270

bypass-github-export-checks

The only missing logic is copied from
```
ATen/native/vulkan/impl/Common.h/cpp
```
to
```
executorch/backends/vulkan/runtime/graph/ops/OpUtils.h/cpp
```

We can create a utils directory and improve their file organization, in a follow up change.
