Add Lock property to drives interface

This change adds the locked property, which is driven the same way the
volumes lock property is driven.

Tested:
busctl introspect xyz.openbmc_project.eStoraged /xyz/openbmc_project/inventory/storage/mmcblk0
.Locked                                     property  b         false                                    emits-change
busctl call xyz.openbmc_project.eStoraged /xyz/openbmc_project/inventory/storage/mmcblk0  xyz.openbmc_project.Inventory.Item.Volume Lock
.Locked                                     property  b         true                                     emits-change
