fluids: Correct PetscOptionsDeprecated usage

It will automatically replace the old option with the new option if
`PetscOptionsDeprecated` is specified before the new option name.

fluids: Make ProblemData a pointer to struct

We basically use it as a pointer-to-struct type everywhere, so might as
well make it consistent with everything else

Many of these are set, but never actually used.

Merge pull request #1371 from CEED/kjansen/DropPotentialFromEtot

Drop Potential Energy from Etot conservation variable

deleted all the unused coordinate references that were throwing warnings

Potential energy removed from all state helpers so no more x (or dx) dependence for them. Interior integrals still need x for IDL but boundary elements don't so removed. This touches lots of qfuncti

Potential energy removed from all state helpers so no more x (or dx) dependence for them. Interior integrals still need x for IDL but boundary elements don't so removed. This touches lots of qfunctions that make state calls and a few problems as well
