Add SolarInputModel to store the data for each tracker and PV
inverter entry in the list. This allows the ListView to just create
one list item for each entry in the model, instead of creating complex
delegates with Column+Repeater objects when showing multiple trackers
for a single solarcharger/multi/inverter service. Also, the model
sorts its items to allow the use of ListView sections for creating the
column headers.

This makes the list load and scroll more quickly, especially when it
contains a large number of trackers.

Also, remove the tracker list from SolarDevice.qml as it is only
required in specific pages, and those can load their own SolarTracker
objects when needed.
