Mobile: add second filter proxy model for dive list

This one significantly reduces the number of dives that are handed to the
ListView in QML. For every trip that isn't expanded (only zero or one trips are
expanded at any time, so almost all the others are collapsed), send only first
dive to the View to allow creation of the section. Hide the rest so we don't
have all these invisible, zero height entries for the vertical dive list.

A big part of this commit is moving a few functions from the DiveListSortModel
to the CollapsedDiveListSortModel. Those are the ones that are needed for the
trip header.
