games-engines/renpy: Update to version 7.3.5

- This is a major update to version 7.3.5.
- Multislot support is dropped since upstream provides backward
  compatibility for older games.
- renpy-7.3.5-use-system-fribidi.patch is based on fribidi patch
  from bug 671008 by Alex <barracuda72@bk.ru>, though it was
  improved further.
