divesummary: add DiveSummary class to shared and backend

Create DiveSummary class in backend-shared and make the DiveSummary calculation
results available to QML.

This adds a loop over all dives (could have been done with a model, but the
models available to mobile are very limited, so use the basic way).

[Dirk Hohndel: renamed the results variable and combined a couple of commits]
