Create a battery icon that loads paths

Create a new battery drawable that will load enough resources from
frameworks/base/core/res/res/ to allow for theming overlays. The current
things are overlayable:

- Perimeter path: the outer shape of the battery (including the
terminal)
- Fill mask: path defining the shape of the fill
- Bolt path: charging bolt path. draws with appropriate protection for
visibilty
- Powersave path: path of the plus sign that draws when in powersave
mode. also draws with protection

Test: visual; sysui demo mode
