[Contextual Edu] Enable updating Edu data in Launcher

- Added ContextualEduStatsManager (in Launcher3) and SystemContextualEduStatsManager(in Quickstep) to enable classes in Launcher3 and quickstep to update contextual edu data
- Implemented new updateContextualEduData method in SystemUiProxy file, so the EduStatsManager could use it for update
- AbsSwipeUpHandler handles the logic to go home/overview when in app. Added code to update contextual edu data when these action is triggered.
