Handle config changes in Launcher
- This is practically a revert to http://ag/c/13687966/5 and refactored to use DisplayController.DisplayInfoChangeListener
- Make Launcher handle size and density change so transition is less janky when screen size changes
- Added fix in RecentsView to update state and TaskView when display profile changes
- Removed 720dp specific resoureces
- Removed unused widget_section_indent
- Removed unnecessary all_apps_background_canvas 600dp override that is not needed in AllApps+
- Moved remaining dp specific into DeviceProfile
- Simplified allowRotation logic to use single variable in DeviceProfile to determine if allow rotation is enabled by default
