lineage-sdk internal: Add LineageNotificationLights

    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.
