CUDA: Do not create CMAKE_CUDA_HOST_COMPILER cache entry
Users can create it through an explicit command-line option if desired.
Initializing the variable as an empty cache entry can wipe out a normal
variable of the same name that may have been set by a toolchain file.
Since commit v3.8.0-rc1~261^2~11 (CUDA: Use the host compiler for
linking CUDA executables and shared libs, 2016-09-19) we save the value
of `CMAKE_CUDA_HOST_COMPILER` persistently in the compiler information
file as a normal variable.
Fixes: #17935
