    SystemUI: Bring back good ol' circle battery style

    * This code is based on the old Java implementation and converted to Kotlin

    * Instead of creating different style within the same drawable
      create one on its own, this makes the code more readable and future proof

    SystemUI: Fix status bar battery icon title

    The wrong string was being picked up which is not capitalized
    and not even localized. Use the already localized string
    from SystemUI package.
