lineage-sdk internal: Add LineageBatteryLights

Browse Source 
Migrate frameworks/base lineage feature
code handling to lineage-sdk.

*) Settings observation and most lineage lights
   feature specific code has been moved to the
   lineage-sdk.

*) Battery frameworks services call out to the
   sdk to allow our features to make changes to
   lights values.
