egl/drm: introduce drm_add_configs_for_visuals() helper
Factor out and rework the existing code so that it prints a debug
message if we have zero configs for any visual.
As a nice side effect we now provide a correct (sequential ID) when
creating a config (via dri2_add_config).
v2: Use correct comparison in loop conditional (Eric)
Use valid C initializer (Gurchetan)
