Add setting to go to sleep after long user inactivity
The European Commision prescribes an auto-standby feature for TV panels:
After some hours of inactivity, the device has to go from on-mode to
standby-mode or off-mode, or another condition not exceeding the
applicable requirements for standby-mode or for off-mode.
After a long time of no user activity the device should go to sleep,
even if wakelocks are held (eg. during video playback).
Test: 1. Set attentive timeout low, to 35s:
`adb shell settings put secure attentive_timeout 35000`
2. Play a YouTube video
3. Observe warning dialog appearing after 5s
4. Verify: Clicking a remote button or changing the setting higher hides
the warning. Remote button press is consumed.
5. Verify: After 35s of not pressing a button the device goes to sleep
6. Verify: If "Stay awake" developer option is enabled, then
warning is not displayed and device does not go to sleep after 35s
7. Verify: No warning or sleep if setting is set to -1
