We are moving to deprecate `ArrayHandleVirtual`, so we are removing the feature where `VariantArrayHandle::CastAndCall` automatically casts to an `ArrayHandleVirtual` if possible. The big reason to make this change now (as opposed to later when `ArrayHandleVirtual` is deprecated) is to improve compile times. This prevents us from having to compile an extra code path using `ArrayHandleVirtual`.
