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

All the memory leaks reported in regression tests via `-malloc_dump`
are now related to the boundary conditions and their handling of
QFunctionCont

fix(fluids): Fix primary PETSc memory leak, others

All the memory leaks reported in regression tests via `-malloc_dump`
are now related to the boundary conditions and their handling of
QFunctionContexts, which is a much more difficult problem and will be
addressed later.

Merge pull request #1543 from CEED/jrwrigh/explicit_stabilized_mass

Fluids: Add stabilized mass operator for advection problem

fluids: Add stabilized mass for advection

This enables "full" SUPG for the advection problem using explicit time
integrators

Merge pull request #1539 from CEED/jrwrigh/explicit_ns

fluids: Make Newtonian BCs compatible with explicit timestepping, add test

fluids: Make BCs compatible with explicit TS

fix(fluids): Enable strong STG for explicit timestepping

Also add error catching if SGS is requested for explicit; it's not
implemented at the moment.

fluids: Refactor function names

- PascalCase for acronyms longer than 2 letters
- Remove the "Anisotropic" qualifier from function names, as we only
have one data-driven SGS model. If we add an isotropic model later, we
can give that the "Isotropic" qualifier on it's function names
- Remove the "Model" qualifier from function names. "SgsDD" is
communicative enough (Subgrid-stress inherently means a model)

fluids: Cleanup advection problems

fluids: Cleanup unused struct members

Many of these are set, but never actually used.

Drop Coordinate Basis from IJacobian (without breaking IDL) (#1380)

* compute IDL coefficient in IFunction that has access to coordinates, append this to jac_data so that IJacobian can avoid pulling
