* allow setting a fixed value anywhere in the domain
* do not use boundaryType but a separate function to check for fixed cell
* set 1.0 on the diagonal in the system matrix and 0.0 for the off-diagonal entries
  to improve numerical accuracy

Implement decision made in !1137:
- 1p gas: `gas`
- 1p liquid: `liq`
- 2p gas/liquid: `gas` and `liq`
- 2p liquid/liquid: `aq` and `napl`
- 3p: `gas`, `aq` and `napl`
- solid: `s`

Add `IsAqueous` to components to detect if a component is aqueous or not.
Adapt reference solutions.
Adjust `primaryVariableName` only where necessary to make the tests pass.
Will be treated in general in !1212.

* only local element needs to be bound

[test][navierstokesnc] Fix test test_msfreeflow. Make binaryDiffusionCoefficient have the same argument as in fluidsystem base class.

* remove now obsolete NavierStokesNCIndices

* index of the pressure has to equal the one of the main component
* advection law does not need outflow information
* fix some reference solutions
