MSim Settings: Update UI/UX with user friendly strings

  Hide TuneAway and Priority subscription preferences unless
  config_HasTuneAway is set to true in device overlay.

  This conditionally reverts cea415df0cf19f9eb3dc1fef16d3a8955584c4f9
  as some device RILs don't support it.

Build V79 - New CM theme provider & chooser
settings: Various cleanups

 * Cleanup display settings ghetto:
   - Move Brightness to the top
   - Replace the single-option menu with a switch in cast screen
   - Create display category
   - Move Cast Screen to higher priority, move down Daydream and Font
   - Create advanced category
   - Relocate advanced stuff to the bottom, including DoubleTap to wake
 * Move gesture settings so it doesn't look like it's part of expanded
   desktop's category
 * Use a seekbar preference to allow setting arbitrary animation scale values

Todo (depend on outstanding draft patches) :

   - Remove Lockscreen wallpaper option from Lockscreen settings
       - Use new ThemeChooser instead
   - Kill Trebuchet sub-settings from Home settings
