Emulated NVMe device updates 

* deallocate or unwritten logical block error feature (me)
   * dataset management command (me)
   * compare command (Gollu Appalanaidu)
   * namespace types (Niklas Cassel)
   * zoned namespaces (Dmitry Fomichev)
   * smart critical warning toggle (Zhenwei Pi)
   * allow cmb and pmr to coexist (me)
   * pmr rds/wds support (Naveen Nagar)
   * cmb v1.4 logic (Padmakar Kalghatgi)
 
 And a lot of smaller fixes from Gollu Appalanaidu and Minwoo Im.
