[Static Runtime] Fix broken test_static_runtime build (#62098)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/62098
The build was broken by D29821533 (https://github.com/pytorch/pytorch/commit/1d2ea76afb4f9ac40c43555da2f3d94dd3549136). The `clamp` overloads used in `deep_wide.h`
are no longer available in the `at::native` namespace.
Use `at::cpu::clamp` and `at::clamp::clip_out` (which should be an alias for
clamp) instead.
