SystemUI: Smart Pixels [1/2]
Disables a percentage of pixels on screen to reduce power consumption.
If enabled with battery saver, don't scale brightness at 0.5f for UX.
Includes:
- Option to enable on battery saver
- User chosen grid
- Burn-in protection
Configurable via overlay and disabled by defualt:
"config_supportSmartPixels"

Smart Pixels: Switch to registered receiver
Switching to a registered receiver allows to properly handle updates
on enabling of battery saver mode and switching of users.
Also only update screen filter with burn-in protection when the
device is in an interactive state.
Test: Service starts after rebooting with it enabled
Service starts on battery saver mode (user toggle)
Service starts on battery saver mode (auto-enabled)
Service re-adjusts on user switch to current user settings
Filter updates after selected timeout

Smart Pixels: Dynamically register receiver
Don't keep the receiver registered if it isn't enabled.

SmartPixels: Use CoreStartable interface for receiver
* Also clean up and add check whether smart pixels is supported.
Signed-off-by: Pranav Vashi <neobuddy89@gmail.com>
SystemUI: Add Smart Pixels tile
Single tap enables/disables.
Long press opens Smart Pixels settings.
User is not allowed to enable or disable when
Smart Pixels has been auto-enabled on battery saver.
