[PRQ#43362] Merge Request for lib32-sdl2_compat12-git

MarsSeed [1] filed a request to merge lib32-sdl2_compat12-git [2] into lib32-sdl12-compat-git [3]: The target package is the one that aligns properly with Arch repo's naming and upstream's name. Also the target package declares the Arch-conforming provides and conflicts entries.
