Partial revert "[HIP] Fix -mllvm option for device lld linker" (#80202)

This partially reverts commit aa964f15
because it caused perf regressions in rccl due to drop of -mllvm
-amgpu-kernarg-preload-count=16 from the linker step. Potentially it
could cause similar regressions for other HIP apps using -mllvm options
with -fgpu-rdc.
