Update DeviceRTL and the AMDGPU plugin to use code
object version 5. Default is code object version 4.

DeviceRTL uses rocm-device-libs instead of directly calling
amdgcn builtins for the functions which are affected by
cov5.

AMDGPU plugin queries the ELF for code object version
and then prepares various implicitargs accordingly.
