SystemUI: Make lockscreen visualizer battery friendly

In case of offloaded playback, the device is allowed to sleep.
However, if the lockscreen visualizer is enabled, the device
hardly enters deep sleep, even if the screen is off. To prevent
this, enable the visualizer only when the lockscreen is shown.

SystemUI: more consistent visualizer logic

- only call setVisible from screen on and screen off methods
- eagerly unregister self to make sure we don't get added twice as a
  listener
- Add some debugging under the DEBUG flag

SystemUI: show visualizer in shade-locked view

This brings back the behavior we had in 12.1 - visualizer would still be
visible in the shade locked state.

Also with the following improvements:
    * use less alpha
    * always attach/detach in a background thread (Async task)
    * use the statusbar state instead keyguard view state listener

Visualizer: Let visualizer fill the entire available screen

* This will allow it to be more dynamic (landscape lock screen for instance)
