During developing bazel build, we discover paddle_util package reference some CUDA headers(basically in Utils.h).

To reproduce this issue, just check out branch feature/bazel_build, then run bazel build paddle/utils:paddle_utils in MacOS, (currently only MacOS is supported).

The screen record is here.

NOTE: We should fix this issue in develop branch because it is not just a bazel building problem.
