  Log Message:
  -----------
  [OpenMP][DeviceRTL] Extract shuffle idiom and port it to declare variant

The shuffle idiom is differently implemented in our supported targets.
To reduce the "target_impl" file we now move the shuffle idiom in it's
own self-contained header that provides the implementation for AMDGPU
and NVPTX. A fallback can be added later on.
