Robert Maynard a4d502a5bf CUDA: Do not device link if CUDA is not an enabled language
Checks added in commit 81b4d10d8f (CUDA: More exhaustive checks to
determine when to do device linking, 2019-05-09, v3.15.0-rc1~82^2)
assumed that CUDA properties would be set only if CUDA is enabled.

We cannot do a device link step if we do not have the CUDA language
enabled.  This was discovered as some projects unconditionally set CUDA
properties such as `CUDA_RESOLVE_DEVICE_SYMBOLS` even when the CUDA
language has not been enabled.

Fixes: #19432
