SystemUI: add a disabled state for Quick Tiles

Some tiles may want to be visible, but not allow any user interaction
due to security reasons. Add a visual disabled state for tiles which are
not enabled.

With this patch, the Profiles tile and the Lockscreen toggle tile
disable themselves on a secure lock screen.
