Previously, `ArrayHandleSOA` worked with any value type that supported `VecTraits`. That means that `ArrayHandleSOA` worked with scalar types like `Float32`. However, for scalar types, the behavior is essentially the same as `ArrayHandleBasic`, but with lots of extra templating and code generation. Although there is nothing _wrong_ with allowing `ArrayHandleSOA` holding a scalar, there is no real reason to either (other than likely template convenience). Generally, there is nothing wrong with supporting it, but if you want to support `ArrayHandleSOA` in places where types are not known (e.g. `Field`), then templating tends to iterate over the cross of all supported types with all supported storage. That means such code will automatically generate a bunch of code for `ArrayHandleSOA` with scalars even if there is no reason for those code paths. So, we can just disable the use of `ArrayHandleSOA` with scalars to allow us to use `ArrayHandleSOA` as a default storage without creating all these useless code paths.
