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.
