SUNDIALS: Use new N_Vector module in ARKode wrapper

[sebproell]

Follow-up to #11654 and part of #11380

Finally, this PR removes the old copy calls from the ARKode module and replaces them with the new N_Vector functionalities from #11395.

Oh... Looks like I need to add the PETSc Vectors to the N_Vector instantiation now. Will open a separate PR when its done.

Sounds good. We will merge that one quickly.

[luca-heltai]

Can you rebase, to check that everything is in place?

[sebproell]

Should I add an entry to the changelog for the collected changes to N_Vector? There is actually some new functionality I didn't explictly mention: ARKode should now support all vector types, including Trilinos and L:d:V., because the new N_Vector implementation supports it.

Yup.

Actually, I will wait with the changelog entry since ARKode isn't yet compiled with those vector types. Will follow up.
