Added the SDL12-Compat backend, using a shim library which implements the `sdl1.2` API over SDL2. The new `sdl12-compat` backend should be used for SDL1 applications when: * the platform doesn't have `dispmanx` anymore (e.g. `rpi` platforms with RaspiOS Bullseye and later) * `sdl2` has a working accelerated video & rendering drivers * not running under `x11` (i.e. KMS) Note: for SDL1+Videocore specific applications, which use directly the dispmanx/legacy GL stack (e.g. `pcsx-rearmed`, `advmame-1.4`, etc.), the backend will not help.
