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.
