Use properties in Asset for MDR V1

Use partNumber, SerialNumber and Manufacturer in Inventory/Decorator/Asset
instead of Inventory/Item/Dimm for MDR V1

Tested:
In https://BMC_IP/redfish/v1/Systems/system/Memory/dimm2
PartNumber, SerialNumber and Manufacturer should show as
{
"@odata.context": "/redfish/v1/$metadata#Memory.Memory",
@odata.id": "/redfish/v1/Systems/system/Memory/dimm2",
"@odata.type": "#Memory.v1_6_0.Memory",
"CapacityMiB": 16384,
"DataWidthBits": 64,
"Id": "dimm2",
"Manufacturer": "Samsung",
"MemoryDeviceType": "DDR4",
"MemoryType": "DRAM",
"Name": "DIMM Slot",
"PartNumber": "M393A2G40DB0-CPB    ",
"SerialNumber": "0209718C",
"Status": {
    "Health": "OK",
    "State": "Enabled"
}
