Add crypto Erase to eStorageD.

The goal is to erase the keys that are used to decrypt the drive. After
the keys are erased it will not be possible to decrypt the drive, even
if the password can be recalled. The data is forever inaccessible.

Testing:

$ systemctl stop emmc.service

$ /eStoraged -b /dev/mmcblk0 &

$ busctl call xyz.openbmc_project.eStoraged.mmcblk0 /xyz/openbmc_project/storage/mmcblk0 xyz.openbmc_project.Inventory.Item.Volume FormatLuks ays 3 1 2 3 xyz.openbmc_project.Inventory.Item.Volume.FilesystemType.ext4
