profile: move max_gas() from DivePlotDataModel to ProfileScene

Browse source 
There is only one user of this - let's remove complex
interdependencies.

Note: there seem to be two independent plot_infos: in the
ProfileScene and in the DivePlotDataModel. To avoid behavioral
change, this keeps using the DivePlotDataModel's version.
In any case, this has to be unified.
