libf2fs_zoned: Introduce f2fs_report_zone() helper function
To prepare for write pointer consistency check by fsck, add
f2fs_report_zone() helper function which calls REPORT ZONE command to
get write pointer status of a single zone. The function is added to
lib/libf2fs_zoned which gathers zoned block device related functions.
