Display Settings: Better font size control

Use a SeekBar instead of a list/spinner to determine the font scaling.
For consistency, an approximate size (small, normal, etc.)
 and the exact percentage are displayed.
Show a preview of the selected font size immediately

settings: Move headset option, hide MoreDeviceSettings if empty

 * This option fits much better in the sound menu under "automation
   and effects", and on many devices it's the only option in the
   "More..." menu under Tap & Pay.
 * Move it, and remove the MoreDeviceSettings top-level category if
   there's nothing else in it.

DisplayColor: Properly handle a minValue

* Previously setting anything as a minValue would cause the
  percentages to get out of whack. For instance, setting it to 35
  would cause the maximum percentage to climb above 100% as well
  as still allowing the value to be set lower than the min.
* This makes the maximum for the slider the max value minus the min
  (so we get the proper spread for min to max) and then adds the min
  back on before setting so we can't possibly go below the min.

Cleanup.

Now that button and keyboard backlight don't use the HW framework
anymore, there's no point in having an abstraction for a single use case.
