Simon Ser 9e98f497af backend/drm: use local DRM FD for wlr_rend
The new wlr_renderer_autocreate API is great for compositors, however
it causes some issues with DRM multi-GPU support.

A DRM child backend wants the compositor to use the parent GPU, so it
exposes the parent's DRM FD in get_drm_fd. However, in order to be able
to perform multi-GPU buffer copies, the child DRM backend still needs to
create a local renderer.

Use the new private wlr_renderer_autocreate_with_drm_fd function to
avoid creating a renderer for the parent GPU.

Fixes: e128e6c08d ("render: drop egl parameters from wlr_renderer_autocreate")
