backend-drm: prepare virtual output API for heterogeneous outputs

Browse Source 
Stop plugins from overwriting the struct weston_output::destroy vfunc,
as that will be used by backends to recognize their outputs.
Instead, pass a plugin-specific destroy callback when creating the
virtual output.

See: https://gitlab.freedesktop.org/wayland/weston/-/issues/268
