fb: add Battery Styles the new way 1/2

google draws now the battery icon which fits perfectly into our
concept. Beside that the batteryview is as well used on QS.
So we readd our battery icons (icon, percentage, icon with percentage
circle, circle perc, dot circle, dot circle perc) back and all are
drawn. As well the icon does not only change on statusbar as well
on QS it is reflected.

As usual color options are present for the User to style the icon

base: layout circle battery percent really in the center

There is no need to use strokeWidth in this layout calculation
