lib: Introduce new parsing rules for ux_locales.c

Introduce new parsing rules for ux_locales.c:ux_locales_get_text():
* Add a version byte: PRERAM_LOCALES_VERSION_BYTE in the beginning. This
  provides more flexibility if we want to change the format of
  preram_locales region.
* Add a new delimiter 0x01 between two string_names. This could fix the
  issue that 'string_name' and 'localized_string' might be the same.

Also fix two bugs:
1. We would search for the language ID exceeding the range of current
   string_name.
2. In 'move_next()', we would exceed the 'size' due to the unconditional
   increase of offset.

Finally, make some minor improvements to some existing comments.
