Refactor iOS builds to facilitate tvOS port

- moved prf files to shared location (uikit, added to QMAKE_PLATFORM)
- prepare some formatting (unconditional blocks mostly) to add conditions later
- make device detection script more generic, passing filter strings
  as a parameter and returning non-os specific variables
