Update all TextAppearance.DeviceDefault styles.

- Directly reference either config_{body,headline}FontFamily attributes
instead of relying on the fontFamily set by material themes (note that
this patch does not actually change any of the fonts for these styles)
- This enables RROs to overlay only config_{body,headline}FontFamily
to change all of TextAppearance.DeviceDefault* styles
