  Reland [HIP] use offload wrapper for non-device-only non-rdc (#132869) (#143964)

Fixed two issues:

1. assertion with -flto. the linker wrapper action is missing for
wrapping the device binary. Added it for -flto.

2. when there are two HIP files, the kernels in the second file were not
found. This is because the -r option of linker wrapper assumes offload
entries section of HIP to be hip_offloading_entries but it is actually
llvm_offload_entries, causing the offload entries sections not made
unique for different object files. Fixed and tested working for both
-fgpu-rdc and -fno-gpu-rdc case with and without -r
