[CUDA][HIP] Emit dependent libs for host only

Recently D60274 was introduced to allow lld to handle dependent libs. However current
usage of dependent libs (e.g. pragma comment(lib, *) in windows header files) are intended
for host only. Emitting the metadata in device IR causes link error in device path.

Until there is a way to different it dependent libs for device or host, metadata for dependent
libs should be emitted for host only. This patch enforces that.
