Kokkos::StaticCrsGraph does not use memory space template parameter passed to KokkosSparse::CrsMatrix

Created by: mndevec

I am providing a device to CrsMatrix in the constructor. This is different than default, where device is either Kokkos::Cuda with hostpinned space, or Kokkos::OpenMP with Kokkos::Hostspace when HBM is enabled.

I was expecting CrsMatrix memory to be allocated at the memory space I provide. However, this holds only for the values view, while row pointers and entries are still allocated at the default memory space of the provided execution space. It seems that StaticCrsGraph do not take the device as template argument, instead it is provided the execution space. It creates a default device, as a result allocated memories diverge for values and entries views.

Shouldn't StaticCrsGraph take the device as template argument instead of execution space?
