Add logs for taskbar and overview split action

Log:
- Taskbar app launch (also from foldeR)
- Taskbar app drag (also from folder)
- Taskbar folder open
- Long press to hide taskbar
- Long press to show taskbar
- Overview Split screen action

Also add support for ActivityContext to overwrite/add to LauncherAtom.ItemInfo, which TaskbarActivityContext does to change HotseatContainer and PredictedHotseatContainer to TaskBarContainer

Test: enable logcat locally
