pitch_detector: cleanup

- cosmetics: remove trailing white space
- mark all functions and variables as static
- merge struct definition and declaration when possible
- rename tuner_settings -> settings (because it's shorter)
- remove unused enums
- don't give pointer to settings struct as argument since there is only
  one struct, same for the settings filename
- fix error cases in settings load:
    reset settings when loading failed
    close file when it hasn't the right size
- inline small load/save functions only used once
- remove unused print_char_xy
- inline print_str and print_int_xy, and use lcd_putsf (added to the
  plugin API)
