examples/fluids: make setup contexts independent

These are now private to each example and can be developed independently.

examples/fluids: consolidate two-step setup

Contexts are created in one place now and we have removed duplicate
struct definitions for physics.

Cleaner density inflow (#953)

Merged onto main this density ONLY inflow step...fixed E_k

Cleaner density inflow (#953)

* density weakly set on the inflow....also seems to have a commit intended for ken/primitiveSUPGterm OOOP

Merged onto main this density ONLY inflow step...fixed E_kinitec bug along the way which used interior velocity.

* first cut at choose your weak inflow rho or T

* cleanup and a missing gamma

* dropped time step to 2e-6, added time limit of 0.001, added suggested parameters for tau constants for linear vs. quadratic. Note this is far from certain, expecially quadratic. Also left commented the required settings to forces SNES to do a fixed number of NL iterations. The current settings do 2 NL iterations for a while then drop to 1 which is ok for steady state but might not be good for SRS.

* potentially better Ctau_{C,M,E} that have much lower oscillations in the free stream even at large time steps like 3.2e-5

* examples/fluids: fix output_freq

* examples/fluids: use bool for weakT

* fix: Add u_normal

* examples/fluids: bug fix in density flux

* examples/fluids: implement "floating" pressure; prescribed u, T

* examples/fluids: fixing initialization

We need has_neumann=true to get the weak boundary integrals called. It
is initialized in problem->setup_ctx and used in SetupLibceed(). This is
a hack to always apply.

* examples/fluids: include kinetic energy in Blasius IC

* examples/fluids: Blasius quasi-2D (slip in z planes)

* feat: Add Exact_Channel function

* examples/fluid: Add Blasius solution calculator

- Added a dedicated ChannelContext, which allows for user setting of
flow parameters and consistent sharing of parameters between
QFunctions (instead of hardcoding)
- Moved density current (DC) specific settings from newtonian.c
densitycurrent.c

* Make gravity into vector quantity

* Add in body force for channel

* examples/fluids: remove explicitly setting coordinate field

This is created automatically now by DMPlex and DMProjectCoordinates
breaks (localized) periodicity, resulting in a tangled mesh.

- Implemented the calculation of Xi for the SUPG term in newtonian.h

* examples/fluids: Remove flux jacobian transpose

- Removed for both eulervortex.h and newtonian.h

* examples/fluids: Reset Newtonian unit scaling to neutral

- Note that this resets the scaling for the densitycurrent problem,
thus the examples (and possibly tests) will probably need to be
changed

* examples/fluids: propose alternative flux Jacobian via prim-to-conservative

* examples/fluids: Add PHASTA diagonal tau

* fix: Add back in timestep obtaining

* examples/fluids: Add analytic tractions to inflow and outflow

- This is a stop-gap until viscous flux can be computed properly on the
boundary from current solution.
- Tau constants in a state of flux still but this produced a decent v at
inflow and outflow, removing the steep dive caused by forcing
dv/dx=-du/dy from a zero traction of omission.

* examples/fluids: Update dt via context labels

* feat: Add more blasius table points

* examples/fluids: Cleanup stab and adjust Ctau_E

* examples/fluids: Correct blasius example CLI

- Also add mention of the `blasius.yaml` file

* examples/fluids: Add supg to default blasius.yaml
