Implement FRURecordTableMetadata and FRURecordTable command
This commit implements the GetFRURecordTableMetadata and GetFRURecordTable
in the PLDM specification DSP0257 for FRU data specification. The FRU table
is populated by the FRU handler class with the configs from the path
/usr/share/pldm/fru.
Tested:
On a Witherspoon system the Get FRURecordTableMetadata and FRURecordTable
command were executed and ensured the FRU table in the command response
matches with the D-Bus inventory properties.
