fluids: Refactor gravity option

- Use `-gravity` instead of `-g`
- Enforce that the input should be a length 3 vector
- Update documentation

Misc: Also update documented default value for `mu`.

fix(fluids): Reset dim before reference_velocity option

If `-g` is not given, then
`PetscOptionsRealArray(..., "-g", ...)`
will set `dim` to zero. This then causes
`PetscOptionsScalarArray(..., "-re

will set `dim` to zero. This then causes

to not read any values.

PetscFE determines basis for examples/fluids/navierstokes (#1264)

* breaking lots of DL stuff to test PetscFE

* fixed missing header

* fluids: Remove unused `Involute` function

* fluids: Set quadrature points for PetscFE

* fluids: Fix GetRestrictionForDomain, Use CreateBasisFromPlex

* fluids: Remove Q_sur arg from SetupStrongBC_Ceed

* fluids: Make shocktube test less brittle

- Small, insignificant changes to the coordinate locations make a
dramatic difference to the initial condition
- For the test case, there is a node right at the midpoint of the
domain. Adding the epsilon fudge factor makes the if statement more
stable

* fluids: Fix SGS test

- Change the test so that it passes on all hardware. It's a very
sentitive test and the changes to the basis creation changed the
initial conditions *just* enough to make the test not happy. Should
really try and make this more robust at some point...

* fluids: Address misc PR comments

* fluids: Remove quad_mode arg from CreateBasisFromPlex

fluids: Remove ComputeL2Projection function

- It's superseded by using `NodalProjectionData` + `ApplyCeedOperator*`

fluids: Don't show partition stats for serial jobs

- It results in nans which may confuse users.
