platform-mc: Terminus name handling

`PLDM-stack: Adding sensor monitoring section` design spec details that
the `Terminus name` is required to create the terminus's sensors,
states, effecters... D-Bus interfaces and `Terminus Name` can be
encoded in the Terminus's `Entity Auxiliary Names PDR` or in the MCTP
Entity-manager endpoint EID configuration file.

Section `28.18 Entity Auxiliary Names PDR` in DSP0248 V1.2.2 details
about the PDRs response for the name of one PLDM entity. When the
containerID is `0x0000` this entity is `Overall system` or `top most
containing entity`. The name of this entity will can be used as
`Terminus name`.

Support parsing `Entity Auxiliary Names PDR` and find the `Terminus
name` if it is reponsed in the terminus' PDRs. `Terminus Name` string
will be assigned to local variable and can be used as prefix for
sensors, state, effecters... names.
