Specialise CUDA API variant scalars into proper scalars.
Some APIs pass scalars as a void* and a cudaDataType_t enumerant. This Specialiser converts those (encapsulated as CudaVariantScalars) into proper Scalars, which are then sent to PtrScalarSpecialiser for further refinement.
Since this Specialiser is inferring the type of arguments, it has a hook which calls the validScalarTypes predicate on the target functor type, giving the functor an opportunity to prune invalid specialisation branches.
