Added ODE diagnostics to FixRxKokkos using Kokkos managed data.
- Added the diagnostics performance analysis routine to FixRxKokkos using Kokkos views.
TODO:
- Switch to using Kokkos data for the per-iteration scratch data. How to allocate only enouch for each work-unit and not all iterations? Can the shared-memory scratch memory work for this, even for large sizes?
