Added __HIP_PLATFORM_AMD__=1 for non JIT build (#4585)

This PR is required in addition to
#4539 to define
HIP_PLATFORM_AMD on ROCm.

This is required for DeepSpeed non-JIT build. For JIT build we have
#4570.

This is required for DeepSpeed extensions build in those docker images
with PyTorch built before
pytorch/pytorch#111975.
