Replace remaining Kokkos::View<T*> by Array<T>

- Remaining Kokkos::View where not related to item or sub-item values
- SubItemValuePerItem now use Array internally

- SubItemValuePerItem<const T>(connectivity) is now invalid since allocated data
is constant. SubItemValuePerItem<const T> is to be used as a view of
SubItemValuePerItem<T>, which can be initialized properly.
