With CUDA 11, the minimum CC version is 3.5 (which we have been using since CUDA 9). With CUDA 12, CC 3.5 is dropped, and 5.0 is now the minimum CC.
Additionally, we bump the GoogleTests C++ standard up to 14 (required for version >= 1.13.0). This should be fine for older versions of GTest as well as, going back to version 1.10.0.
