  [Clang][AMDGPU] Restore the non-RDC compilation pipeline

The new offload driver uses the LTO compilation pipeline even for non-RDC
compilation. This PR restores the conventional non-RDC flow, where the backend
generates executable code directly, which is then bundled into the HIP fat
binary.

We can revert this change in the future if we decide to deprecate the
distinction between non-RDC and RDC compilation and unify the compilation flow.
