backends: implement custom EGL and renderer initialization 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

Remove wlr_create_renderer_func_t This callback allowed compositors to customize the EGL config used by the renderer. However with renderer v6 EGL configs aren't used anymore. Instead, buffers are allocated via GBM and GL FBOs are rendered to. So customizing the EGL config is a no-op.

backend/drm: remove special linear case for cursor plane We now properly mark the cursor plane's formats as linear-only, and we now have a version of wlr_drm_format_intersect that handles the case of linear-only formats and implicit modifiers. We can remove the special drm_plane_init_surface flag we had for cursor planes. This also allows us to use a non-linear layout for cursor planes on drivers that support it. Tested on amdgpu GFX9.
