Require CMAKE_CXX_USE_RESPONSE_FILE_FOR_OBJECTS=ON in CUDA, complex ON, ETI ON build

@mhoemmen I have PR #149 up to check that CMAKE_CXX_USE_RESPONSE_FILE_FOR_OBJECTS=ON for the CUDA, complex ON, ETI ON build, and if not tell users to enable this.

From trilinos/Trilinos#2141 it seems the decision is to let users enable this CMake option rather than set it as default due to potential issues depending on combos of OS, CMake version and compiler see NOTE bottom of TribitsBuildReference

Is PR #149 sufficient to resolve this issue?

Adding @srajama1 to discussion.

@ndellingwood I left some comments on PR #149 that address your questions. I would prefer that kokkos-kernels check for now, as long as that works for all tested host compiler options in CUDA builds.

Based on the comments in the above referenced Trilinos issue and the comment about gfortran and CMake, let us just request the user to set it and reconfigure. I will add it to my list of annoyances and complain in about it on bad days :)

We should at least update the limited "documentation" we have so whoever is enabling complex knows this ahead. Let us do that and push this.
