this existed for historical reasons, but realistically now it should be possible to build mesa with dri3 always enabled. additionally, this check was often used as a substitute for having drm functionality, which is sort of similar but also not really a direct match this simplifies a bunch of conditionals and prevents users from footgunnning themselves into orbit Reviewed-by: Adam Jackson <ajax@redhat.com> Reviewed-by: Eric Engestrom <eric@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30952>
