- Send the notification light info up to SystemUI from NoMan.
- Doze mode will now periodically pulse the display (once)
if the notification light is active.
- Change "tease" terminology to "pulse", which is the singular.
Maintain the multi-pulse on buzz-beep-blink for now as extra
emphasis.
- Scrim controller now always takes number of pulses as an arg,
to support a single pulse (used for notification light, and
eventually pickup once available).
- Dial down the display brightness when pulsing.
