platform-mc: discovery FRU data from terminus

As [1], `pldmd` will host Fru D-Bus inventory object path and Fru
`xyz.openbmc_project.Inventory.Decorator.*` D-Bus interfaces of one PLDM
terminus.
[1] https://github.com/openbmc/docs/blob/master/designs/pldm-stack.md#processing-pldm-fru-information-sent-down-by-the-host-firmware

Support getting FRU data from terminus in the terminus discovery phase
and expose FRU data to the Fru D-Bus properties in
`xyz.openbmc_project.Inventory.Decorator.Asset`,
`xyz.openbmc_project.Inventory.Decorator.AssetTag`,
`xyz.openbmc_project.Inventory.Decorator.Compatible` and
`xyz.openbmc_project.Inventory.Decorator.Revision` interfaces of
`xyz/openbmc_project/FruPldm/<Terminus_Name>` D-Bus object path which is
created by `xyz.openbmc_project.PLDM` D-Bus service. The object path
will be available until the endpoint EID is removed from the MCTP
D-Bus.
