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

fluids: Make MatShell functions static

This is done primarily to allow MatCeed to coexist with the context
operators for right now.

This has the nasty side-effect of forcing `Mat` objects to be NUL

Testing with GDB, the `Mass_N` QFunction is only called when creating

fluids: Remove convergence test from velocity_gradient_projection

Testing with GDB, the `Mass_N` QFunction is only called when creating
the rowsum preconditioner and isn't called afterwards. This is true with
or without the convergence test. So I've removed the convergence test as
it's not necessary
