native: skip SDL3 path by default — opt in via AC_USE_SDL=1

SDL3 was always-attempted at boot with crash-recovery fallback. The
dlopen + Mesa DRI loader + SDL_Init + window/renderer creation costs
real time on every cold boot and offers no measurable visual benefit
on the hardware we ship — DRM dumb buffers do the same thing faster
and don't pull a GLES context full of failure modes (the partial-init
state when SDL starts but Mesa's renderer doesn't was almost certainly
the source of the "garbled chars on boot" the user reported).

Now opt-in via AC_USE_SDL=1. Default = straight to DRM. The whole SDL3
loader code path is preserved (sdl_init/sdl_load/crash handler) for
when we want it back; it just doesn't run.
