f2fs-tools: support to set and recognize CP_TRIMMED_FLAG

During mkfs, once we have issued discard for all device, we can set
CP_TRIMMED_FLAG in cp pack, this can make kernel module to record
undiscard blocks correctly, it will help to avoid unneeded discard.

Also this patch makes f2fs-tools be with the ability of recognizing
that new flag.
