Add optional SDL3 support while keeping SDL2 as the default. SDL3 builds must be selected explicitly with the SYSTEM3_SDL_VERSION CMake option. Centralize most SDL2/SDL3 API differences behind compatibility interfaces. Audio playback uses a dedicated SDL3 backend based on SDL3 audio streams, implemented separately in mako_sdl3.cpp. Android and Nintendo Switch remain on SDL2 for now.
