pldmtool: Add new entity types in the pdr support list

Added new entity types in the GetPDR command interface to parse
the newly added entity types. Added new types for disk backplane,
fan, nvme drive, dimm, tod battery, pcie slot and pcie cable card.

Testing Result for some entity types:

pldmtool platform GetPDR -d 156
{
    "nextRecordHandle": 157,
    "responseCount": 27,
    "recordHandle": 156,
    "PDRHeaderVersion": 1,
    "PDRType": "State Sensor PDR",
    "recordChangeNumber": 0,
    "dataLength": 17,
    "PLDMTerminusHandle": 0,
    "sensorID": 55,
    "entityType": "Slot",
    "entityInstanceNumber": 1,
    "containerID": 3,
    "sensorInit": "noInit",
    "sensorAuxiliaryNamesPDR": false,
    "compositeSensorCount": 1,
    "stateSetID[0]": "17",
    "possibleStatesSize[0]": 1,
    "possibleStates[0]": " 1 2"
}

pldmtool platform GetPDR -d 170
