Remove deprecated GEOM classes
Follow-up on r322318 and r322319 and remove the deprecated modules. Shift some now-unused kernel files into userspace utilities that incorporate them. Remove references to removed GEOM classes in userspace utilities. Reviewed by: imp (earlier version) Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D21249
