  Revert "[AMDGPU][LTO] Assume closed world after linking (#105845)"

We can't assume closed world even in full LTO post-link stage. It is only true
if we are building a "GPU executable". However, AMDGPU does support "dyamic
library". I'm not aware of any approach to tell if it is relocatable link when
we create the pass. For now let's revert the patch. We can re-enable it once we
can handle it correctly.
