platform-mc: Support GetPLDMVersion
`GetPLDMCommands` in DSP0240 v1.1.0 requires the PLDM supported type
version. In the current implementation, when detecting new MCTP
endpoint, `pldmd` always send `0xff 0xff 0xff 0xff` version to
`GetPLDMCommand` in discovery steps with the assumption that the
terminus will response for the request with any version of PLDM type.
Some termini don't accept `0xff 0xff 0xff 0xff` as input
version to `GetPLDMCommands` command because value `0xff` only has
meaning `A value of 0xFF in the "update" field indicates that the field
to be ignored.` in the `Section 12.6.1 Version field encoding` in `MCTP
Base spec` DSP0236 v1.3.1 but not in `PLDM base spec` DSP0240 v1.1.0
where `GetPLDMCommand` is detailed.
Support sending `GetPLDMVersion` from the supported PLDM types of one
terminus in the `discovery step` to get the PLDM version. And use that
version as input for `GetPLDMCommands` of that PLDM types to get
the supported PLDM commands.
