Tpetra::CrsGraph::getLocalDiagOffsets: Deprecate ArrayRCP version
Created by: mhoemmen

BlockCrsMatrix::getLocalDiagCopy (which uses the output of getLocalDiagOffsets) takes the offsets in as Kokkos::View, not Teuchos::ArrayRCP. Thus, we don't need the latter version of getLocalDiagOffsets, so we can deprecate it.
