[Win][Build] There is Cyclic dependencies error when build with BUILD_SEPARATE_OPS=true

### 🐛 Describe the bug

When build PyTorch on windows, there two modes: BUILD_SEPARATE_OPS or not.
In release build case, BUILD_SEPARATE_OPS is false. It's passed in building on windows.
But when set BUILD_SEPARATE_OPS=true or CMAKE_BUILD_TYPE is "Debug", the build mode BUILD_SEPARATE_OPS will lead to error:
```
CMake Error: The inter-target dependency graph contains the following strongly connected component (cycle):
"torch_xpu" of type SHARED_LIBRARY
depends on "torch_xpu_ops" (weak)
"torch_xpu_ops" of type STATIC_LIBRARY
depends on "torch_xpu" (weak)
At least one of these targets is not a STATIC_LIBRARY. Cyclic dependencies are allowed only among static libraries.
CMake Generate step failed. Build files cannot be regenerated correctly.
```

Reproduce:
Apply following diff in torch_xpu_ops, and build again.
```
diff --git a/CMakeLists.txt b/CMakeLists.txt
index 8f6fa8d6..033a47d5 100644
