scsi: sd_zbc: Move ZBC declarations to scsi_proto.h

Move standard macro definitions for the zone types and zone conditions
to scsi_proto.h together with the definitions related to the REPORT
ZONES command. While at it, define all values in the enums to be clear.

Also remove unnecessary includes in sd_zbc.c.

No functional change is introduced by this patch.
