local() and mapped_value() operators (as part of mapped reduction) only work using native nebo backend.
mapped_value() Nebo operators introduced as part of the
NeboMappedReduction operation, do not work on Kokkos because they depend on the outer index that is determined as part of the outer loop in case of the native nebo backend. Since we lose control of the outer loop when using Kokkos, information needed to drive
mapped_value() operators are no longer available.
