AdvancedDisplay: Fix strings

* It just so happens that not all devices will have the
  same options available, so allow them to specify what
  they have without breaking tranlations by moving the
  scenario names into individual strings from the arrays
* Update a few strings to be actually translatable
* Fix an off-by-one error for every display mode after
  "LineageOS (default)": UI is the same thing as the
  default mode, so remove it to make the mode selection
  actually choose the user-selected mode
