  [Driver][HIP] Do not pass -dependency-file flag for HIP Device offloading

When we launch hipcc with multiple offload architectures along with -MF dep_file flag, the clang compilation invocations for host and device offloads write to the same dep_file, and can lead to collision during file IO operations. This can typically happen during large workloads.
This commit provides a fix to generate dep_file only in host compilation.
