  cmake: Drop ENABLE_SDL_GPU option

The code conditionals using SDL_gpu in the source tree are unmaintained
and likely broken. From past discussions with vultraz and Aginor, the
plan ahead is to completely drop SDL_gpu and its support code once
there's no risk of conflict with certain WIP branches.
