In an attempt to pull more of EGLConfig choosing into one place, refactor code into the new gl_renderer_get_egl_config(). The purpose of this function is to find an EGL config that not only satisfies the requested attributes and the pixel formats if given but also makes sure the config is generally compatible with the single GL context we have. All this was already checked in gl_renderer_create_window_surface(), but gl_renderer_create_pbuffer_surface() is still missing it. This patch is preparation for fixing the pbuffer path. We explicitly replace visual_id with drm_formats, because that is what they really are. Only the DRM backend passes in other than NULL/0, and if other backends start caring about the actual pixel format, drm_format is the lingua franca.
