Pull Request resolved: https://github.com/pytorch/pytorch/pull/63625
This change adds a static runtime's native op implementation for `aten::detach` op.
See the standard `aten::detach`'s implementation (https://codebrowser.bddppq.com/pytorch/pytorch/aten/src/ATen/native/TensorShape.cpp.html#_ZN2at6native6detachERKNS_6TensorE ) for comparison.
Test Plan:
- Added `StaticRuntime.IndividualOps_Detach`.
- Observed
