Add --hip-link to target_id check

The new driver in clang does not automatically link against the HIP libraries, so we need to add a --hip-link option here to enforce linking. Otherwise we'll get an error on the link stem of check_cxx_compiler_flag() when calling with "-xhip" and "--offload-arch"

Note: The link step isn't really needed for this use case, as invalid targets will fail the compilation step. But check_cxx_compiler_flag() performs both compiling and linking by default
