bmcweb:Check for dimm presense for State Attribute

The state attribute was showing Enabled even if dimm was not present.

Added Present property under Inventory Item interface to read the dimm
presence and accordingly populate jsonValue["Status"]["State"]
to Enabled or Absent.

Tested:
-Get of redfish/v1/Systems/system/Memory/dimm shows correct
State values in both the cases.
-Redfish validator passed.
