[llvm] [AMDGPU] Update libc/runtime target to use amdgpu (PR #210032)

[via llvm-commits]

https://github.com/LU-JOHN created https://github.com/llvm/llvm-project/pull/210032

Update libc/runtime targets to use "amdgpu" instead of "amdgcn".  This change is necessary to do libc testing with a check-libc-amdgpu-amd-amdhsa target.  The previous check-libc-amdgcn-amd-amdhsa target already does not work.
