* WIP: Fluids - use FluxInviscid_fwd() for computing the flux jacobean

strong_conv is not reproduced and stab is not computed correctly

* WIP: working on variational notation for stabilization

* Fluids - fix missing parts after rebasing onto main

* Fluids - fix SU in the IFunction

* Fluids - refactor stabilization

* Fluids - move stab helper functions to stabilization.h

* Fluids - minor style

* Fluids - minor refactor

* Fluids - add regression test for primitive variables

* Fluids - use UnpackState_*()

* Fluids - more refactoring of stabilization

* Fluids - DC: use utility functions

* Fluids - refactor total flux

* Fluids - minor cleanup

* Fluids - set x[0] = 0 for channel to exclude gravitational potential

* Fluids - updated stabilization.h

* Fluids - zero strong_conv before pass it to FluxInviscidStrong() to be safe

* Fluids - move switch-case for STAB to a helper function

* Fluids - rename Y -> R in Stabilization*()

* Fluids - fix stab sign in RHS
