[CS] 6/N=6: Remove CSI's wallpaper tracking & CS#setLockscreenUser.

Now that all classes are migrated to WallpaperRepository, we can remove
CentralSurfaceImpl's wallpaper tracking. We can also remove
CentralSurfaces#setLockscreenUser, because that method was only used to
re-fetch the current wallpaper (which is now no longer done in
CentralSurfaces).
