Camera2: Smart scene icons w. original artwork

These are functional replacements for the smart scene indicators
created from scratch for CM, and fully owned by the project.

I'm sure the size, border weight may need some adjustment, but
they're currently identical to the burst mode indicators in:

camera: Add metadata-based ASD

 * New cameras use the metadata callback to report the
   detected scene mode. Add support for this.
 * The asdModes array must be set for this to work, which
   should contain the ordered list of possible scenes,
   corresponding to the camera_asd_values array.

camera: Histogram, ZSL burst mode, HDR-on-ZSL

 * Optional features available on newer sensors
 * Histogram needs to be made pretty
