Create QsInfo and SbInfo boxes for MobileSignalController

Simplify MobileSignalController#notifyListeners() by splitting the QS
and SB portions of the method into their own *Info objects and moving
those calls out to their own methods.

Also adds mNetworkToIconLookup, mProviderModelBehavior, and
mProviderModelSetting to the MobileSignalController logs.
