  [HIP] Fix -mllvm option for device lld linker

currently clang passes -mllvm options to the device lld linker plugin
when compiling HIP. This is against default clang behavior
which is only passing -mllvm options to linker plugin specified through -Wl
options. This patch lets clang only pass -Xoffload-linker -mllvm= options
to device lld linker plugin.
