gate torch_global_deps with BUILD_SHARED_LIBS flag (#32011)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/32011
Run into build problem with Ninja + code analysis build as follows:
```
The install of the torch_global_deps target requires changing an RPATH from
the build tree, but this is not supported with the Ninja generator unless
on an ELF-based platform.
```
Seems we don't need build the target for static build mode?
Verified code analyzer works with the patch.
