Do not emit compile-time error if attemping to use MKL utils with unsupported scalar types. This can be considered a temporary fix because the proper TPL wrappers using unification layer will not instantiate MKL wrappers for unsupported types in the first place. In particular, this is coming for SpGEMM.

Do not emit compile-time error if attemping to use MKL utils with unsupported scalar types. These changes were suggested by @maartenarnst .
This can be considered a temporary fix because the proper TPL wrappers using unification layer will not instantiate MKL wrappers for unsupported types in the first place. In particular, this is coming for SpGEMM.
@trilinos/kokkos-kernels
Motivation
Replaces compile-time error with runtime exception. When using Tpetra::CrsMatrix with Scalar being something other than float/double/complex_float/complex_double (which is perfectly fine), KokkosKernels shouldn't be trying to instantiate any MKL utils/wrappers for those scalar types. But since it is, replacing with runtime error instead is a reasonable fix for now.
For the 4.0 release, the MKL SpGEMM wrappers will go through the unification layer and only get instantiated for supported type combinations, so these can become static_asserts once again.
