Tests: Don't unnecessarily set CUDA_ARCHITECTURES

Architecture 30 was removed with CUDA 11, so most of the CUDA tests fail with
it.
Remove setting the architecture and bump the minimum version to 3.18, so
CMP0104 takes effect and we can rely on the default architecture, which is
guaranteed to be compilable.

Use of __ldg() in ProperLinkFlags was removed as it only affects performance
and is available only on sm_35 and above.

Testing the functionality of CUDA_ARCHITECTURES is already covered by
CudaOnly.Architecture and CudaOnly.CompileFlags.
