* update to SDL 3.2.0

* remove SDL wrap

* fix darwin and windows CI

* update build box, correct msys sdl3 dependency

* port leftovers from renderer backend to SDL3

* ci: use 7z to create zip

* renwindow: create texture and surface suitable for the display

* system: remove trailing whitespace

* renderer: fix trailing whitespace

* system: fix checking the wrong argument

* system: port rmdir and stat to SDL3 API

* system: remove unneeded API level check
