Title: [lipstick] When the screen is switched on show a notification about the current thermal state if not shown yet

Logic:
- When a thermal warning occurs, show the notification (and play the associated sound) regardless of the display state
- When the display is switched on, show a notification about the current thermal state (if it results in one) if a notification about the current thermal state has not been shown yet while the display was on
