Split ApplicationInfo into ApplicationInfo which is used for AllAppsView and ShortcutInfo which is

used for the workspace.

Consolidate the three icon resampling functions into one.

Ensure that the icons stored in LauncherProvider are the right size, so we don't have to resample
them each time we load them.
