It seems nvcc allows non-array type const var to be used in device code but not

I don't see why we cannot use array type const var in device code if we are
able to emit them on device side. There may be CUDA/HIP code already using this
feature. Disabling it may cause regressions.
On the other hand, I think disallow extern const var in device code is
reasonable, since we do not know how it is initialized.
