[locale] Port TZ widget lookup to new find() method

Browse Source 
- The TZ widget uses a different coordinate system (mapping lat and lon
  to pixel locations, and then calculating Manhattan distance from
  that), so needs a different distance function.
- Simplify code: there's just one "closest TZ" function.
