Minor fixes to Launcher

- Tweaking the AllApps tab padding
- Fixing issue where the cling punch out might be in the wrong location
- Removing unused dragging code related to drop/scroll area overlap
- Tweaking padding so that picking up an icon on the top row does not automatically hover over delete (Bug 5636264)
- Fixing issue where multiple bgs in AllApps tab bar line makes it look blurry (Bug 5523822)
