Add support for LocationCode

LocationCode is needed to populate ServiceLabel by BMCWeb for Redfish
resource associated with eStorage.
LocationCode is derived from config object exported by Entity Manager
in the the following interface:
    "xyz.openbmc_project.Configuration.EmmcDevice

To surface LocationCode, the "Exposes" entry in board's Entity Manager
config can add "LocationCode" property as follows:
{
    "Name": "example_emmc",
    "Type": "EmmcDevice",
    "LocationCode": "U1000"
}

Here the LocationCode is the silk screen label.

Tested:

busctl introspect xyz.openbmc_project.eStoraged \
/xyz/openbmc_project/inventory/storage/mmcblk0  \
xyz.openbmc_project.Inventory.Decorator.LocationCode

NAME                TYPE      SIGNATURE RESULT/VALUE FLAGS

    },
    "Name": "mmcblk0",

    },

    },
    "PredictedMediaLifeLeftPercent": 100,
    "Status": {
    "State": "Enabled"
    }
}

eStoraged

This daemon serves as an abstraction for an encrypted storage device, encapsulating the security functionality and providing a D-Bus interface to manage the encrypted filesystem on the device. Using the D-Bus interface, other software components can interact with eStoraged to do things like create a new encrypted filesystem, wipe its contents, lock/unlock the device, or change the password.
