Compositors now have more control over how the backend creates its renderer. Currently all backends create an EGL/GLES2 renderer, so the necessary attributes for creating the context are passed to a user-provided callback function. It is responsible for initializing provided wlr_egl and to return a renderer. On fail, return 0. Fixes #987
